|
from archives.

<description>
|
|
<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>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All GNU Tar users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/tar-1.23"
|
|
</code>
|
|
|
|
<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.
