 Mandriva Linux Security Advisory                         MDVSA-2009:271

 Package : libnasl
 Date    : October 12, 2009
 Affected: Corporate 4.0

 Problem Description:

 A vulnerability has been found and corrected in libnasl:
 nasl/nasl_crypto2.c in the Nessus Attack Scripting Language library
 (aka libnasl) 2.2.11 does not properly check the return value from
 the OpenSSL DSA_do_verify function, which allows remote attackers to
 bypass validation of the certificate chain via a malformed SSL/TLS
 signature, a similar vulnerability to CVE-2008-5077 (CVE-2009-0125).
 This update fixes this vulnerability.
