Package : libtasn1-6
CVE ID : CVE-2015-3622

Hanno Boeck discovered a heap-based buffer overflow flaw in the way
Libtasn1, a library to manage ASN.1 structures, decoded certain
DER-encoded input. A specially crafted DER-encoded input could cause an
application using the Libtasn1 library to crash, or potentially to
execute arbitrary code.

For the stable distribution (jessie), this problem has been fixed in
version 4.2-3+deb8u1.

For the testing distribution (stretch), this problem has been fixed in
version 4.4-3.

For the unstable distribution (sid), this problem has been fixed in
version 4.4-3.

We recommend that you upgrade your libtasn1-6 packages.
