Detail
| Evgeny Legerov discovered several out-of-bounds memory accesses in the DER decoding component component of the Tiny ASN.1 Library that allows attackers to crash the DER decoder and possibly execute arbitrary code. The old stable distribution (woody) is not affected by these problems. For the stable distribution (sarge) these problems have been fixed in version 2_0.2.10-3sarge1. For the unstable distribution (sid) these problems will be fixed soon. We recommend that you upgrade your gnutls packages. |
