DSA-1795 ldns -- buffer overflowID: oval:org.secpod.oval:def:600314 | Date: (C)2011-05-13 (M)2022-10-10 |

Stefan Kaltenbrunner discovered that ldns, a library and set of utilities to facilitate DNS programming, did not correctly implement a buffer boundary check in its RR DNS record parser. This weakness could enable overflow of a heap buffer if a maliciously-crafted record is parsed, potentially allowing the execution of arbitrary code. The scope of compromise will vary with the context in which ldns is used, and could present either a local or remote attack vector. The old stable distribution is not affected by this issue. For the stable distribution , this problem has been fixed in version 1.4.0-1+lenny1. For the unstable distribution , this problem was fixed in version 1.5.1-1. We recommend that you upgrade your ldns packages.
