CVE-2010-2946
Published: 29 September 2010
fs/jfs/xattr.c in the Linux kernel before 2.6.35.2 does not properly handle a certain legacy format for storage of extended attributes, which might allow local users by bypass intended xattr namespace restrictions via an "os2." substring at the beginning of a name.
From the Ubuntu security team
Sergey Vlasov discovered that JFS did not correctly handle certain extended attributes. A local attacker could bypass namespace access rules, leading to a loss of privacy.
