Scientific Linux Security Update : glibc on SL5.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.
