<package name="sys-fs/e2fsprogs" auto="yes" arch="*">

<background>
<p>e2fsprogs is a set of utilities for maintaining the ext2, ext3 and ext4
file systems.
</p>
</background>
<description>
<p>A heap-based buffer overflow was discovered in openfs.c in the libext2fs
library in e2fsprogs.
</p>
</description>
<impact type="normal">
<p>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.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All e2fsprogs users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-fs/e2fsprogs-1.42.12"
</code>
