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

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.

Synopsis :

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

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.

Risk factor :

Low / CVSS Base Score : 2.1
