FreeBSD : e2fsprogs -- heap buffer overflow (299e3f81-aee7-11dc-b781-0016179b2dd5)
Medium Nessus Plugin ID 29769
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionTheodore 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.
SolutionUpdate the affected package.
