|
|
gzip (GNU zip) is a popular compression program. The included
|
|
zgrep utility allows you to grep gzipped files in place.
|

<description>
|
|
<p>
|
|
The gzip and gunzip programs are vulnerable to a race condition
|
|
when setting file permissions (CAN-2005-0988), as well as improper
|
|
handling of filename restoration (CAN-2005-1228). The zgrep utility
|
|
improperly sanitizes arguments, which may come from an untrusted source
|
|
(CAN-2005-0758).
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
These vulnerabilities could allow arbitrary command execution,
|
|
changing the permissions of arbitrary files, and installation of files
|
|
to an aribitrary location in the filesystem.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All gzip users should upgrade to the latest stable version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/gzip-1.3.5-r6"</code>
|
|
</resolution>
