A heap-based buffer overflow in e2fsprogs could result in execution of arbitrary code.
|Package||sys-fs/e2fsprogs on all architectures|
|Affected versions||< 1.42.13|
|Unaffected versions||>= 1.42.13|
e2fsprogs is a set of utilities for maintaining the ext2, ext3 and ext4 file systems.
e2fsprogs has a heap-based buffer overflow in closefs.c in the libext2fs library.
A local attacker could execute arbitrary code via a specially crafted block group descriptor.
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-1.42.13"
