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

Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


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).

Solution :

Update the affected packages.

Risk factor :

Low / CVSS Base Score : 2.1
(CVSS2#AV:L/AC:L/Au:N/C:N/I:N/A:P)
