SUSE SLES11 Security Update : kernel (SUSE-SU-2018:2907-1)

Medium Nessus Plugin ID 117823

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 SP3 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-2018-10940: 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-2018-15572: 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).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
