Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Forced Integer Overflow This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

NASL family SuSE Local Security Checks NASL id SUSE_SU-2019-1829-1.NASL description The SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack could have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. [bnc#1140575] CVE-2019-10639: The Linux kernel used to allow Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely by the attacker forcing the target device to send UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping).

[bnc#1134395] CVE-2019-10126: A heap-based buffer overflow in the wireless driver code was fixed. This issue might have lead to memory corruption and possibly other consequences. [bnc#1136935] CVE-2019-11599: The coredump implementation did not use locking or other mechanisms to prevent vma layout or vma flags changes while it ran, which allowed local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. [bnc#1131645]. CVE-2019-12614: There was an unchecked kstrdup of prop->name on PowerPC platforms, which allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). [bnc#1137194] CVE-2018-16871: A flaw was found in the NFS implementation. An attacker who was able to mount an exported NFS filesystem was able to trigger a NULL pointer dereference by an invalid NFS sequence. This could panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will were lost. [bnc#1137103] CVE-2019-12819: The function __mdiobus_register() used to call put_device(), which would trigger a fixed_mdio_bus_init use-after-free error. This would cause a denial of service. [bnc#1138291] CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller did not check for this, it could trigger a NULL pointer dereference. This would cause denial of service. [bnc#1138293] CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main() allowed local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a 'double fetch' vulnerability. [bsc#1136922] CVE-2019-12380: An issue was in the EFI subsystem existed that mishandled memory allocation failures. Note, however, that all relevant code runs only at boot-time, before any user processes are started. Therefore, there was no possibility for an unprivileged user to exploit this issue.

This update introduces a new sysctl value to control the minimal MSS (net.ipv4.tcp_min_snd_mss), which by default uses the formerly hard coded value of 48. We recommend raising this to 536 unless you know that your network requires a lower value. - CVE-2019-11486 Jann Horn of Google reported numerous race conditions in the Siemens R3964 line discipline. A local user could use these to cause unspecified security impact. This module has therefore been disabled. - CVE-2019-11599 Jann Horn of Google reported a race condition in the core dump implementation which could lead to a use-after-free. A local user could use this to read sensitive information, to cause a denial of service (memory corruption), or for privilege escalation. - CVE-2019-11815 It was discovered that a use-after-free in the Reliable Datagram Sockets protocol could result in denial of service and potentially privilege escalation. This protocol module (rds) is not auto loaded on Debian systems, so this issue only affects systems where it is explicitly loaded. - CVE-2019-11833 It was discovered that the ext4 filesystem implementation writes uninitialised data from kernel memory to new extent blocks. A local user able to write to an ext4 filesystem and then read the filesystem image, for example using a removable drive, might be able to use this to obtain sensitive information. - CVE-2019-11884 It was discovered that the Bluetooth HIDP implementation did not ensure that new connection names were null-terminated. A local user with CAP_NET_ADMIN capability might be able to use this to obtain sensitive information from the kernel stack. last seen 2020-06-01 modified 2020-06-02 plugin id 125959 published 2019-06-18 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125959 title Debian DSA-4465-1 : linux - security update (SACK Panic) (SACK Slowness) NASL family SuSE Local Security Checks NASL id SUSE_SU-2019-1854-1.NASL description The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: In the Linux kernel, a device could be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses (bnc#1140575 1140577). CVE-2019-10639: The Linux kernel allowed Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping).

An attacker could use this to construct a malicious HFS+ image that, when mounted, could cause a denial of service (system crash). (CVE-2018-14617) Vasily Averin and Pavel Tikhomirov discovered that the cleancache subsystem of the Linux kernel did not properly initialize new files in some situations.

The following security bugs were fixed : CVE-2019-10638: In the Linux kernel, a device could be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses (bnc#1140575 1140577). CVE-2019-10639: The Linux kernel allowed Information Exposure (partial kernel address disclosure), that lead to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack could be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping).

CVE-2019-3846, CVE-2019-10126 huangwen reported multiple buffer overflows in the Marvell wifi (mwifiex) driver, which a local user could use to cause denial of service or the execution of arbitrary code. CVE-2019-5489 Daniel Gruss, Erik Kraft, Trishita Tiwari, Michael Schwarz, Ari Trachtenberg, Jason Hennessey, Alex Ionescu, and Anders Fogh discovered that local users could use the mincore() system call to obtain sensitive information from other processes that access the same memory-mapped file. CVE-2019-11477 Jonathan Looney reported that a specially crafted sequence of TCP selective acknowledgements (SACKs) allows a remotely triggerable kernel panic. CVE-2019-11478 Jonathan Looney reported that a specially crafted sequence of TCP selective acknowledgements (SACKs) will fragment the TCP retransmission queue, allowing an attacker to cause excessive resource usage. CVE-2019-11479 Jonathan Looney reported that an attacker could force the Linux kernel to segment its responses into multiple TCP segments, each of which contains only 8 bytes of data, drastically increasing the bandwidth required to deliver the same amount of data. This update introduces a new sysctl value to control the minimal MSS (net.ipv4.tcp_min_snd_mss), which by default uses the formerly hard- coded value of 48. We recommend raising this to 512 unless you know that your network requires a lower value. (This value applies to Linux 3.16 only.) CVE-2019-11810 It was discovered that the megaraid_sas driver did not correctly handle a failed memory allocation during initialisation, which could lead to a double-free. This might have some security impact, but it cannot be triggered by an unprivileged user. CVE-2019-11833 It was discovered that the ext4 filesystem implementation writes uninitialised data from kernel memory to new extent blocks. A local user able to write to an ext4 filesystem and then read the filesystem image, for example using a removable drive, might be able to use this to obtain sensitive information. CVE-2019-11884 It was discovered that the Bluetooth HIDP implementation did not ensure that new connection names were null-terminated.

CVE-2019-3846, CVE-2019-10126 huangwen reported multiple buffer overflows in the Marvell wifi (mwifiex) driver, which a local user could use to cause denial of service or the execution of arbitrary code. CVE-2019-5489 Daniel Gruss, Erik Kraft, Trishita Tiwari, Michael Schwarz, Ari Trachtenberg, Jason Hennessey, Alex Ionescu, and Anders Fogh discovered that local users could use the mincore() system call to obtain sensitive information from other processes that access the same memory-mapped file. CVE-2019-9500, CVE-2019-9503 Hugues Anguelkov discovered a buffer overflow and missing access validation in the Broadcom FullMAC wifi driver (brcmfmac), which a attacker on the same wifi network could use to cause denial of service or the execution of arbitrary code. CVE-2019-11477 Jonathan Looney reported that a specially crafted sequence of TCP selective acknowledgements (SACKs) allows a remotely triggerable kernel panic. CVE-2019-11478 Jonathan Looney reported that a specially crafted sequence of TCP selective acknowledgements (SACKs) will fragment the TCP retransmission queue, allowing an attacker to cause excessive resource usage. CVE-2019-11479 Jonathan Looney reported that an attacker could force the Linux kernel to segment its responses into multiple TCP segments, each of which contains only 8 bytes of data, drastically increasing the bandwidth required to deliver the same amount of data. This update introduces a new sysctl value to control the minimal MSS (net.ipv4.tcp_min_snd_mss), which by default uses the formerly hard- coded value of 48. We recommend raising this to 536 unless you know that your network requires a lower value. CVE-2019-11486 Jann Horn of Google reported numerous race conditions in the Siemens R3964 line discipline. A local user could use these to cause unspecified security impact. This module has therefore been disabled. CVE-2019-11599 Jann Horn of Google reported a race condition in the core dump implementation which could lead to a use-after-free. A local user could use this to read sensitive information, to cause a denial of service (memory corruption), or for privilege escalation. CVE-2019-11815 It was discovered that a use-after-free in the Reliable Datagram Sockets protocol could result in denial of service and potentially privilege escalation. This protocol module (rds) is not auto- loaded on Debian systems, so this issue only affects systems where it is explicitly loaded. CVE-2019-11833 It was discovered that the ext4 filesystem implementation writes uninitialised data from kernel memory to new extent blocks. A local user able to write to an ext4 filesystem and then read the filesystem image, for example using a removable drive, might be able to use this to obtain sensitive information. CVE-2019-11884 It was discovered that the Bluetooth HIDP implementation did not ensure that new connection names were null-terminated. A local user with CAP_NET_ADMIN capability might be able to use this to obtain sensitive information from the kernel stack.

This could lead to a local elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-66954097.(CVE-2017-13216) - A certain backport in the TCP Fast Open implementation for the Linux kernel before 3.18 does not properly maintain a count value, which allow local users to cause a denial of service (system crash) via the Fast Open feature, as demonstrated by visiting the chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through 3.16.x kernel builds, including longterm-maintenance releases and ckt (aka Canonical Kernel Team) builds.(CVE-2015-3332) - The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message.(CVE-2016-4486) - The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access.(CVE-2017-5897) - In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when using the RXRPC keys incorrectly assumes the size of a field. This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. This could possibly lead to memory corruption and possible privilege escalation.(CVE-2017-7482) - A flaw was found in the Linux Kernel where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients.(CVE-2018-14625) - drivers/net/usb/asix_devices.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device.(CVE-2017-16647) - A memory leak in the ql_alloc_large_buffers() function in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux kernel before 5.3.5 allows local users to cause a denial of service (memory consumption) by triggering pci_dma_mapping_error() failures, aka CID-1acb8f2a7a9f.(CVE-2019-18806) - An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR.(CVE-2018-7755) - The usbvision driver in the Linux kernel package 3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red Hat Enterprise Linux (RHEL) 7.1 allows physically proximate attackers to cause a denial of service (panic) via a nonzero bInterfaceNumber value in a USB device descriptor.(CVE-2015-7833) - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network.(CVE-2019-3846) - drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.(CVE-2019-16232) - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.(CVE-2019-16234) - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.(CVE-2019-16231) - Insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver before version 21.10 may allow an unauthenticated user to potentially enable denial of service via adjacent access.(CVE-2019-0136) - A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiex_uap_parse_tail_ies function in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other consequences.(CVE-2019-10126) - The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation.

The following security bugs were fixed : CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack could have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. [bnc#1140575] CVE-2019-10639: The Linux kernel used to allow Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely by the attacker forcing the target device to send UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping).
