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)

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 discover...

CVE-2010-2071

The btrfsxattrsetacl function in fs/btrfs/acl.c in btrfs in the Linux kernel 2.6.34 and earlier does not check file ownership before setting an ACL, which allows local users to bypass file permissions by setting arbitrary ACLs, as demonstrated using setfacl...
