Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : glibc, eglibc vulnerabilities (USN-944-1)

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Ubuntu host is missing one or more security-related patches.


Maksymilian Arciemowicz discovered that the GNU C library did not correctly handle integer overflows in the strfmon function. If a user or automated system were tricked into processing a specially crafted format string, a remote attacker could crash applications, leading to a denial of service. (Ubuntu 10.04 was not affected.) (CVE-2008-1391)

Jeff Layton and Dan Rosenberg discovered that the GNU C library did not correctly handle newlines in the mntent family of functions. If a local attacker were able to inject newlines into a mount entry through other vulnerable mount helpers, they could disrupt the system or possibly gain root privileges. (CVE-2010-0296)

Dan Rosenberg discovered that the GNU C library did not correctly validate certain ELF program headers. If a user or automated system were tricked into verifying a specially crafted ELF program, a remote attacker could execute arbitrary code with user privileges.

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.


Update the affected packages.
