Package : bind9
Vulnerability : improper assert
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2009-0696
CERT advisory : VU#725188
Debian Bug : 538975
It was discovered that the BIND DNS server terminates when processing a specially crafted dynamic DNS update. This vulnerability affects all
BIND servers which serve at least one DNS zone authoritatively, as a
master, even if dynamic updates are not enabled. The default Debian configuration for resolvers includes several authoritative zones, too,
so resolvers are also affected by this issue unless these zones have
been removed.
For the old stable distribution (etch), this problem has been fixed in
version 9.3.4-2etch5.
For the stable distribution (lenny), this problem has been fixed in
version 9.5.1.dfsg.P3-1.
For the unstable distribution (sid), this problem has been fixed in
version 1:9.6.1.dfsg.P1-1.
We recommend that you upgrade your bind9 packages.
