<p>SWI-Prolog is a free, small, and standard compliant Prolog compiler.</p>
<p>Multiple vulnerabilities have been discovered in SWI-Prolog:
* An error in the canoniseFileName() function could cause a stack-based
buffer overflow (CVE-2012-6089).
* An error in the expand() function could cause a stack-based buffer
overflow (CVE-2012-6090).
<impact type="normal">
<p>A context-dependent attack can create files with specially crafted
names, causing arbitrary code execution or a denial of service condition.
<p>There is no known workaround at this time.</p>
<p>All SWI-Prolog users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=dev-lang/swi-prolog-6.2.5"
