Gmane

Subject: Security ERRATA Low: glibc on SL5.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Thursday 25th April 2013 14:05:45 UTC (over 3 years ago)
Synopsis:          Low: glibc security and bug fix update
Advisory ID:       SLSA-2013:0769-1
Issue Date:        2013-04-24
CVE Numbers:       CVE-2013-0242
                   CVE-2013-1914
--

It was found that getaddrinfo() did not limit the amount of stack memory
used during name resolution. An attacker able to make an application
resolve an attacker-controlled hostname or IP address could possibly cause
the application to exhaust all stack memory and crash. (CVE-2013-1914)

A flaw was found in the regular expression matching routines that process
multibyte character input. If an application utilized the glibc regular
expression matching mechanism, an attacker could provide specially-crafted
input that, when processed, would cause the application to crash.
(CVE-2013-0242)

This update also fixes the following bugs:

* The improvements made in a previous update to the accuracy of floating
point
functions in the math library caused performance regressions for those
functions. The performance regressions were analyzed and a fix was applied
that retains the current accuracy but reduces the performance penalty to
acceptable levels.

* It was possible that a memory location freed by the localization code
could be accessed immediately after, resulting in a crash. The fix ensures
that the application does not crash by avoiding the invalid memory access.
