Mandriva Linux Security Advisory MDVSA-2009:271
Package : libnasl
Date : October 12, 2009
Affected: Corporate 4.0
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.
To upgrade automatically use MandrivaUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
All packages are signed by Mandriva for security. You can obtain the
GPG public key of the Mandriva Security Team by executing:
