Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected libc6 package.
