<title>GNU Tar: User-assisted execution of arbitrary code</title>
<synopsis>A buffer overflow flaw in GNU Tar could result in execution of
arbitrary code or a Denial of Service.

<vulnerable range="lt">1.23</vulnerable>
<p>GNU Tar is a utility to create archives as well as add and extract files
from archives.
<p>GNU Tar is vulnerable to a boundary error in the rmt_read__ function in
lib/rtapelib.c, which could cause a heap-based buffer overflow.
<impact type="normal">
<p>A remote attacker could entice the user to load a specially crafted
archive, possibly resulting in the execution of arbitrary code or a
Denial of Service.
<p>There is no known workaround at this time.</p>
<p>All GNU Tar users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=app-arch/tar-1.23"
<p>NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since July 18, 2010. It is likely that your system is already
no longer affected by this issue.
