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

Ubuntu Security Notice (C) 2010-2016 Canonical, Inc. / NASL script (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

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.
(CVE-2010-0830).

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 :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
