Ubuntu 4.10 / 5.04 : linux-source-2.6.10, linux-source-2.6.8.1 vulnerabilities (USN-137-1)

Low Nessus Plugin ID 20529

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6

Synopsis

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

Description

Alexander Nyberg discovered that ptrace() insufficiently validated addresses on the amd64 platform so that it was possible to set an invalid segment base. A local attacker could exploit this to crash the kernel. This does not affect the i386 and powerpc platforms in any way. (CAN-2005-0756)

Chris Wright discovered that the mmap() function could create illegal memory maps (using the 'mmap' function) with the start address pointing beyond the end address. A local user could exploit this to crash the kernel or possibly even execute arbitrary code with kernel privileges. (CAN-2005-1265).

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 packages.
