SUSE-SU-2018:3088-1

Описание

The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various security and bugfixes.

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-2018-10940: 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-2018-15594: Ensure correct handling of indirect calls, to prevent attackers for conducting Spectre-v2 attacks against paravirtual guests (bsc#1105348)
• CVE-2018-15572: The spectre_v2_select_mitigation function did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517)
• 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-2018-14734: ucma_leave_multicast accessed a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bsc#1103119)
