A heap-based buffer overflow in e2fsprogs might allow local attackers to execute arbitrary code.

e2fsprogs is a set of utilities for maintaining the ext2, ext3 and ext4 file systems.
A heap-based buffer overflow was discovered in openfs.c in the libext2fs library in e2fsprogs.
A remote attacker could entice a user to use ext2fs library (for example, fsck) on a specially crafted Ext2/3/4 file system possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All e2fsprogs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-fs/e2fsprogs-1.42.12"
