Ubuntu 8.04 LTS : glibc regression (USN-1589-2)

medium Nessus Plugin ID 63285

Language:

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).

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.
