CVE-2011-2928
Published: 29 August 2011
The befs_follow_link function in fs/befs/linuxvfs.c in the Linux kernel before 3.1-rc3 does not validate the length attribute of long symlinks, which allows local users to cause a denial of service (incorrect pointer dereference and OOPS) by accessing a long symlink on a malformed Be filesystem.
From the Ubuntu Security Team
Time Warns discovered that long symlinks were incorrectly handled on Be filesystems. A local attacker could exploit this with a malformed Be filesystem and crash the system, leading to a denial of service.
