Cscope is a developer utility used to browse and manage source
|
|
code.

<description>

|
<p>
|
|
Cscope creates temporary files in world-writable directories with
|
|
predictable names.
|
|
</p>
|
|

|
|
<impact type="normal">
|
|
<p>
|
|
A local attacker could create symbolic links in the temporary
|
|
files directory, pointing to a valid file somewhere on the filesystem.
|
|
When Cscope is executed, this would result in the file being
|
|
overwritten with the rights of the user running the utility, which
|
|
could be the root user.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Cscope users should upgrade to the latest version:
|
|

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-util/cscope-15.5-r2"</code>
