Ubuntu Security Notice (C) 2012-2014 Canonical, Inc. / NASL script (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

USN-1589-1 fixed vulnerabilities in the GNU C Library. One of the
updates exposed a regression in the floating point parser. This update
fixes the problem.

We apologize for the inconvenience.

It was discovered that positional arguments to the printf() family of
functions were not handled properly in the GNU C Library. An attacker
could possibly use this to cause a stack-based buffer overflow,
creating a denial of service or possibly execute arbitrary code.
(CVE-2012-3404, CVE-2012-3405, CVE-2012-3406)

It was discovered that multiple integer overflows existed in
the strtod(), strtof() and strtold() functions in the GNU C
Library. An attacker could possibly use this to trigger a
stack-based buffer overflow, creating a denial of service or
possibly execute arbitrary code. (CVE-2012-3480).

Solution :

Update the affected libc6 package.

Risk factor :

Medium / CVSS Base Score : 6.8
