A local user can take advantage of this flaw to cause a denial of service (memory consumption). - CVE-2018-6555 A flaw was discovered in the irda_setsockopt function in the irda subsystem, allowing a local user to cause a denial of service (use-after-free and system crash). - CVE-2018-7755 Brian Belleville discovered a flaw in the fd_locked_ioctl function in the floppy driver in the Linux kernel. The floppy driver copies a kernel pointer to user memory in response to the FDGETPRM ioctl. A local user with access to a floppy drive device can take advantage of this flaw to discover the location kernel code and data. - CVE-2018-9363 It was discovered that the Bluetooth HIDP implementation did not correctly check the length of received report messages. A paired HIDP device could use this to cause a buffer overflow, leading to denial of service (memory corruption or crash) or potentially remote code execution. - CVE-2018-9516 It was discovered that the HID events interface in debugfs did not correctly limit the length of copies to user buffers. A local user with access to these files could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. However, by default debugfs is only accessible by the root user. - CVE-2018-10902 It was discovered that the rawmidi kernel driver does not protect against concurrent access which leads to a double-realloc (double free) flaw. A local attacker can take advantage of this issue for privilege escalation. - CVE-2018-10938 Yves Younan from Cisco reported that the Cipso IPv4 module did not correctly check the length of IPv4 options. On custom kernels with CONFIG_NETLABEL enabled, a remote attacker could use this to cause a denial of service (hang). - CVE-2018-13099 Wen Xu from SSLab at Gatech reported a use-after-free bug in the F2FS implementation. An attacker able to mount a crafted F2FS volume could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation. - CVE-2018-14609 Wen Xu from SSLab at Gatech reported a potential NULL pointer dereference in the F2FS implementation. An attacker able to mount a crafted F2FS volume could use this to cause a denial of service (crash). - CVE-2018-14617 Wen Xu from SSLab at Gatech reported a potential NULL pointer dereference in the HFS+ implementation. An attacker able to mount a crafted HFS+ volume could use this to cause a denial of service (crash). - CVE-2018-14633 Vincent Pelletier discovered a stack-based buffer overflow flaw in the chap_server_compute_md5() function in the iSCSI target code. An unauthenticated remote attacker can take advantage of this flaw to cause a denial of service or possibly to get a non-authorized access to data exported by an iSCSI target. - CVE-2018-14678 M. Vefa Bicakci and Andy Lutomirski discovered a flaw in the kernel exit code used on amd64 systems running as Xen PV guests. A local user could use this to cause a denial of service (crash). - CVE-2018-14734 A use-after-free bug was discovered in the InfiniBand communication manager. A local user could use this to cause a denial of service (crash or memory corruption) or possible for privilege escalation. - CVE-2018-15572 Esmaiel Mohammadian Koruyeh, Khaled Khasawneh, Chengyu Song, and Nael Abu-Ghazaleh, from University of California, Riverside, reported a variant of Spectre variant 2, dubbed SpectreRSB. A local user may be able to use this to read sensitive information from processes owned by other users. - CVE-2018-15594 Nadav Amit reported that some indirect function calls used in paravirtualised guests were vulnerable to Spectre variant 2. A local user may be able to use this to read sensitive information from the kernel. - CVE-2018-16276 Jann Horn discovered that the yurex driver did not correctly limit the length of copies to user buffers. A local user with access to a yurex device node could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. - CVE-2018-16658 It was discovered that the cdrom driver does not correctly validate the parameter to the CDROM_DRIVE_STATUS ioctl. A user with access to a cdrom device could use this to read sensitive information from the kernel or to cause a denial of service (crash). - CVE-2018-17182 Jann Horn discovered that the vmacache_flush_all function mishandles sequence number overflows. A local user can take advantage of this flaw to trigger a use-after-free, causing a denial of service (crash or memory corruption) or privilege escalation. last seen 2020-06-01 modified 2020-06-02 plugin id 117862 published 2018-10-02 reporter This script is Copyright (C) 2018-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/117862 title Debian DSA-4308-1 : linux - security update code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Debian Security Advisory DSA-4308.

The following security bugs were fixed : CVE-2018-14634: Prevent integer overflow in create_elf_tables that allowed a local attacker to exploit this vulnerability via a SUID-root binary and obtain full root privileges (bsc#1108912) CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870) CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in yurex_read allowed local attackers to use user access read/writes to crash the kernel or potentially escalate privileges (bsc#1106095) CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922) CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001) CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903) CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689) CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511) CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509) CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322) CVE-2018-10879: A local user could have caused a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact by renaming a file in a crafted ext4 filesystem image (bsc#1099844) CVE-2018-10883: A local user could have caused an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099863) CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could have used this to cause a system crash and a denial of service (bsc#1099845) CVE-2018-10882: A local user could have caused an out-of-bound write, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image (bsc#1099849) CVE-2018-10881: A local user could have caused an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099864) CVE-2018-10877: Prevent out-of-bound access in the ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem image (bsc#1099846) CVE-2018-10876: A use-after-free was possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image (bsc#1099811) CVE-2018-10878: A local user could have caused an out-of-bounds write and a denial of service or unspecified other impact by mounting and operating a crafted ext4 filesystem image (bsc#1099813) CVE-2018-10853: The KVM hypervisor did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could have used this flaw to potentially escalate privileges inside guest (bsc#1097104). The update package also includes non-security fixes.

This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001) CVE-2018-13094: Prevent OOPS that may have occured for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp (bnc#1100000) CVE-2018-13095: Prevent denial of service (memory corruption and BUG) that could have occurred for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999) CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922) CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689) CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511) CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509) CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol (bnc#1096748) CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service (bnc#1096748) CVE-2018-10938: A crafted network packet sent remotely by an attacker forced the kernel to enter an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service (bnc#1106016) The update package also includes non-security fixes.
