Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : linux, linux-{source-2.6.15,ec2,mvl-dove,ti-omap} vulnerabilities (USN-966-1)

High Nessus Plugin ID 48253

Synopsis

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

Description

Junjiro R. Okajima discovered that knfsd did not correctly handle strict overcommit. A local attacker could exploit this to crash knfsd, leading to a denial of service. (Only Ubuntu 6.06 LTS and 8.04 LTS were affected.) (CVE-2008-7256, CVE-2010-1643)

Chris Guo, Jukka Taimisto, and Olli Jarva discovered that SCTP did not correctly handle invalid parameters. A remote attacker could send specially crafted traffic that could crash the system, leading to a denial of service. (CVE-2010-1173)

Mario Mikocevic discovered that GFS2 did not correctly handle certain quota structures. A local attacker could exploit this to crash the system, leading to a denial of service. (Ubuntu 6.06 LTS was not affected.) (CVE-2010-1436)

Toshiyuki Okajima discovered that the kernel keyring did not correctly handle dead keyrings. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-1437)

Brad Spengler discovered that Sparc did not correctly implement non-executable stacks. This made userspace applications vulnerable to exploits that would have been otherwise blocked due to non-executable memory protections. (Ubuntu 10.04 LTS was not affected.) (CVE-2010-1451)

Dan Rosenberg discovered that the btrfs clone function did not correctly validate permissions. A local attacker could exploit this to read sensitive information, leading to a loss of privacy. (Only Ubuntu 9.10 was affected.) (CVE-2010-1636)

Dan Rosenberg discovered that GFS2 set_flags function did not correctly validate permissions. A local attacker could exploit this to gain access to files, leading to a loss of privacy and potential privilege escalation. (Ubuntu 6.06 LTS was not affected.) (CVE-2010-1641)

Shi Weihua discovered that btrfs xattr_set_acl function did not correctly validate permissions. A local attacker could exploit this to gain access to files, leading to a loss of privacy and potential privilege escalation. (Only Ubuntu 9.10 and 10.04 LTS were affected.) (CVE-2010-2071)

Andre Osterhues discovered that eCryptfs did not correctly calculate hash values. A local attacker with certain uids could exploit this to crash the system or potentially gain root privileges. (Ubuntu 6.06 LTS was not affected.) (CVE-2010-2492).

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.
