Debian 7 Wheezy: DLA-950-1 Critical GnuTLS LibTasn1 Buffer Issue
debian lts
May 23, 2017
Secunia Research has discovered multiple vulnerabilities in GnuTLS libtasn1, which can be exploited by malicious people to compromise a vulnerable system
Topics Covered
Summary
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.
