Debian Security Advisory
DSA-2440-1 libtasn1-3 -- missing bounds check
- Date Reported:
- 24 Mar 2012
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2012-1569.
- More information:
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.
