<title>Cscope: Insecure creation of temporary files</title>
Cscope is vulnerable to symlink attacks, potentially allowing a local user
to overwrite arbitrary files.

Cscope is a developer utility used to browse and manage source
Cscope creates temporary files in world-writable directories with
predictable names.
<impact type="normal">
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.
There is no known workaround at this time.
All Cscope users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-util/cscope-15.5-r2&quot;</code>
