MGASA-2016-0079 - Updated glibc packages fix security vulnerabilities

Publication date: 19 Feb 2016
URL: http://advisories.mageia.org/MGASA-2016-0079.html

Type: security
Affected Mageia releases: 5
CVE: CVE-2014-9761,
     CVE-2015-7547,
     CVE-2015-8776,
     CVE-2015-8777,
     CVE-2015-8778,
     CVE-2015-8779

Description:
Updated glibc fixes the following security issues:

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

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

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 (CVE-2015-8776).

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 (CVE-2015-8777).

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 (CVE-2015-8778).

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 (CVE-2015-8779).
