CVE-2015-3622: Buffer Overflow
First published: Mon May 04 2015(Updated: )
A heap-based buffer overflow flaw was found in the way the libtasn1 library decoded certain DER-encoded input. A specially crafted, DER-encoded input could cause an application using libtasn1 to perform an invalid read, causing the application to crash. Upstream patch: <a href="http://git.savannah.gnu.org/gitweb/?p=libtasn1.git;a=commitdiff;h=f979435823a02f842c41d49cd41cc81f25b5d677">http://git.savannah.gnu.org/gitweb/?p=libtasn1.git;a=commitdiff;h=f979435823a02f842c41d49cd41cc81f25b5d677</a>
