Mandriva Linux Security Advisory 2010-076 - The ssl3_get_record function in ssl/s3_pkt.c in OpenSSL 0.9.8f through 0.9.8m allows remote attackers to cause a denial of service (crash) via a malformed record in a TLS connection. OpenSSL before 0.9.8m does not check for a NULL return value from bn_wexpand function calls which has unspecified impact and context-dependent attack vectors. The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but Kerberos configuration files cannot be opened, could allow remote attackers to cause a denial of service (NULL pointer dereference and daemon crash). Finally, this update provides support for secure renegotiation, preventing men-in-the-middle attacks. Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products. Packages for 2009.0 are provided due to the Extended Maintenance Program.

Problem Description:

This update fixes several security issues in openssl:
- The ssl3_get_record function in ssl/s3_pkt.c in OpenSSL 0.9.8f
through 0.9.8m allows remote attackers to cause a denial of service
(crash) via a malformed record in a TLS connection (CVE-2010-0740)
- OpenSSL before 0.9.8m does not check for a NULL return value
from bn_wexpand function calls which has unspecified impact and
context-dependent attack vectors (CVE-2009-3245)
- The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL
before 0.9.8n, when Kerberos is enabled but Kerberos configuration
files cannot be opened, could allow remote attackers to cause a denial
of service (NULL pointer dereference and daemon crash) (CVE-2010-0433)
- Finally, this update provides support for secure renegotiation,
preventing men-in-the-middle attacks (CVE-2009-3555).

Packages for 2008.0 and 2009.0 are provided due to the Extended
Maintenance Program for those products.

Update:

Packages for 2009.0 are provided due to the Extended Maintenance
