SUSE SLED12 / SLES12 Security Update : glibc (SUSE-SU-2016:0471-1)

critical Nessus Plugin ID 88832
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

This update for glibc fixes the following security issues :

- CVE-2015-7547: A stack-based buffer overflow in getaddrinfo allowed remote attackers to cause a crash or execute arbitrary code via crafted and timed DNS responses (bsc#961721)

- CVE-2015-8777: Insufficient checking of LD_POINTER_GUARD environment variable allowed local attackers to bypass the pointer guarding protection of the dynamic loader on set-user-ID and set-group-ID programs (bsc#950944)

- CVE-2015-8776: Out-of-range time values passed to the strftime function may cause it to crash, leading to a denial of service, or potentially disclosure information (bsc#962736)

- CVE-2015-8778: Integer overflow in hcreate and hcreate_r could have caused an out-of-bound memory access. leading to application crashes or, potentially, arbitrary code execution (bsc#962737)

- CVE-2014-9761: A stack overflow (unbounded alloca) could have caused applications which process long strings with the nan function to crash or, potentially, execute arbitrary code. (bsc#962738)

- CVE-2015-8779: A stack overflow (unbounded alloca) in the catopen function could have caused applications which pass long strings to the catopen function to crash or, potentially execute arbitrary code. (bsc#962739)

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.
