VuXML ID	Description
299e3f81-aee7-11dc-b781-0016179b2dd5	e2fsprogs -- heap buffer overflow Theodore Y. Ts'o reports: Fix a potential security vulnerability where an untrusted filesystem can be corrupted in such a way that a program using libext2fs will allocate a buffer which is far too small. This can lead to either a crash or potentially a heap-based buffer overflow crash. No known exploits exist, but main concern is where an untrusted user who possesses privileged access in a guest Xen environment could corrupt a filesystem which is then accessed by thus allowing the untrusted user to gain privileged access in the host OS. Thanks to the McAfee AVERT Research group for reporting this issue.
