Vulnerability Insight:
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)
