Debian Security Advisory DSA-2440-1 security@debian.org
http://www.debian.org/security/ Florian Weimer
March 24, 2012 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : libtasn1-3
Vulnerability : missing bounds check
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-1569
Matthew Hall discovered that many callers of the asn1_get_length_der
function did not check the result against the overall buffer length
before processing it further. This could result in out-of-bounds
memory accesses and application crashes. Applications using GNUTLS
are exposed to this issue.
For the stable distribution (squeeze), this problem has been fixed in
version 2.7-1+squeeze+1.
For the unstable distribution (sid), this problem has been fixed in
version 2.12-1.
We recommend that you upgrade your libtasn1-3 packages.
