Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2017-2863.NASL description From Red Hat Security Advisory 2017:2863 : An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely. (CVE-2017-7541, Moderate) Bug Fix(es) : * Previously, removal of a rport during ISCSI target scanning could cause a kernel panic. This was happening because addition of STARGET_REMOVE to the rport state introduced a race condition to the SCSI code. This update adds the STARGET_CREATED_REMOVE state as a possible state of the rport and appropriate handling of that state, thus fixing the bug. As a result, the kernel panic no longer occurs under the described circumstances. (BZ# 1472127) * Previously, GFS2 contained multiple bugs where the wrong inode was assigned to GFS2 cluster-wide locks (glocks), or the assigned inode was cleared incorrectly. Consequently, kernel panic could occur when using GFS2. With this update, GFS2 has been fixed, and the kernel no longer panics due to those bugs. (BZ#1479397) * Previously, VMs with memory larger than 64GB running on Hyper-V with Windows Server hosts reported potential memory size of 4TB and more, but could not use more than 64GB. This was happening because the Memory Type Range Register (MTRR) for memory above 64GB was omitted. With this update, the /proc/mtrr file has been fixed to show correct base/size if they are more than 44 bit wide. As a result, the whole size of memory is now available as expected under the described circumstances.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es) : * Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. (CVE-2017-7184, Important) * A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. (CVE-2017-1000111, Important) * An exploitable memory corruption flaw was found in the Linux kernel. The append path can be erroneously switched from UFO to non-UFO in ip_ufo_append_data() when building an UFO packet with MSG_MORE option. If unprivileged user namespaces are available, this flaw can be exploited to gain root privileges. (CVE-2017-1000112, Important) * Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely. (CVE-2017-7541, Moderate) * An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate) * A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace. (CVE-2017-7558, Moderate) * The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to possibly cause a situation where a value may be used after being freed (use-after-free) which may lead to memory corruption or other unspecified other impact. (CVE-2017-11176, Moderate) * A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. (CVE-2017-14106, Moderate) * A flaw was found where the XFS filesystem code mishandles a user-settable inode flag in the Linux kernel prior to 4.14-rc1. This can cause a local denial of service via a kernel panic. (CVE-2017-14340, Moderate) Red Hat would like to thank Chaitin Security Research Lab for reporting CVE-2017-7184; Willem de Bruijn for reporting CVE-2017-1000111; and Andrey Konovalov for reporting CVE-2017-1000112. The CVE-2017-7558 issue was discovered by Stefano Brivio (Red Hat) and the CVE-2017-14340 issue was discovered by Dave Chinner (Red Hat).

A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. - Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing. - A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. - Andrey Konovalov discovered a race condition in the UDP Fragmentation Offload (UFO) code in the Linux kernel. A local attacker could use this to cause a denial of service or execute arbitrary code. - Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. - The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to possibly cause a situation where a value may be used after being freed (use after free) which may lead to memory corruption or other unspecified other impact. - The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel before 4.12 allows local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path.

The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution.The flaw requires firewire-net module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network.(CVE-2016-8633i1/4%0 - It was found that the Linux kernel can hit a BUG_ON() statement in the __xfs_get_blocks() in the fs/xfs/xfs_aops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUG_ON() instead of an I/O failure. This allows a local unprivileged attacker to cause a system crash and a denial of service.(CVE-2016-10741i1/4%0 - A vulnerability was found in the Linux kernel. The pointer to the netlink socket attribute is not checked, which could cause a null pointer dereference when parsing the nested attributes in function tipc_nl_publ_dump(). This allows local users to cause a DoS.(CVE-2016-4951i1/4%0 - It was reported that with Linux kernel, earlier than version v4.10-rc8, an application may trigger a BUG_ON in sctp_wait_for_sndbuf if the socket tx buffer is full, a thread is waiting on it to queue more data, and meanwhile another thread peels off the association being used by the first thread.(CVE-2017-5986i1/4%0 - The kvm_vm_ioctl_check_extension function in arch/powerpc/kvm/powerpc.c in the Linux kernel before 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) via a KVM_CHECK_EXTENSION KVM_CAP_PPC_HTM ioctl call to /dev/kvm.(CVE-2017-15306i1/4%0 - A flaw was found in the way the Linux kernel last seen 2020-03-19 modified 2019-05-14 plugin id 124970 published 2019-05-14 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/124970 title EulerOS Virtualization for ARM 64 3.0.1.0 : kernel (EulerOS-SA-2019-1517) NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2017-3659.NASL description The remote Oracle Linux host is missing a security update for the Unbreakable Enterprise kernel package(s). last seen 2020-06-05 modified 2017-12-14 plugin id 105247 published 2017-12-14 reporter This script is Copyright (C) 2017-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/105247 title Oracle Linux 6 / 7 : Unbreakable Enterprise kernel (ELSA-2017-3659) (BlueBorne) (Dirty COW) (Stack Clash) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2017-2863.NASL description An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely. (CVE-2017-7541, Moderate) Bug Fix(es) : * Previously, removal of a rport during ISCSI target scanning could cause a kernel panic. This was happening because addition of STARGET_REMOVE to the rport state introduced a race condition to the SCSI code. This update adds the STARGET_CREATED_REMOVE state as a possible state of the rport and appropriate handling of that state, thus fixing the bug. As a result, the kernel panic no longer occurs under the described circumstances. (BZ# 1472127) * Previously, GFS2 contained multiple bugs where the wrong inode was assigned to GFS2 cluster-wide locks (glocks), or the assigned inode was cleared incorrectly. Consequently, kernel panic could occur when using GFS2. With this update, GFS2 has been fixed, and the kernel no longer panics due to those bugs. (BZ#1479397) * Previously, VMs with memory larger than 64GB running on Hyper-V with Windows Server hosts reported potential memory size of 4TB and more, but could not use more than 64GB. This was happening because the Memory Type Range Register (MTRR) for memory above 64GB was omitted. With this update, the /proc/mtrr file has been fixed to show correct base/size if they are more than 44 bit wide. As a result, the whole size of memory is now available as expected under the described circumstances.
