Package : libtasn1-3
Version : 2.13-2+deb7u4
CVE ID : CVE-2017-6891
Secunia Research has discovered multiple vulnerabilities in GnuTLS
libtasn1, which can be exploited by malicious people to compromise
a vulnerable system.
Two errors in the "asn1_find_node()" function (lib/parser_aux.c)
can be exploited to cause a stacked-based buffer overflow.
Successful exploitation of the vulnerabilities allows execution
of arbitrary code but requires tricking a user into processing
a specially crafted assignments file by e.g. asn1Coding utility.
For Debian 7 "Wheezy", this problem has been fixed in version
2.13-2+deb7u4.
We recommend that you upgrade your libtasn1-3 packages.
Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
