Exploitation of this issue may lead to arbitrary code execution. This issue is not believed to be exploitable with the pre-built kernel images provided by Debian, but it might be an issue for custom images built from the Debian-provided source package. http://www.linuxsecurity.com/content/view/138229 * Debian: New Linux 2.6.18 packages fix overflow conditions (Jun 9) ----------------------------------------------------------------- Wei Wang from McAfee reported a potential heap overflow in the ASN.1 decode code that is used by the SNMP NAT and CIFS subsystem.

A flaw was found in the way ucd-snmp checked an SNMPv3 packet's Keyed-Hash Message Authentication Code (HMAC). An attacker could use this flaw to spoof an authenticated SNMPv3 packet. (CVE-2008-0960) This update has been rated as having moderate security impact by the Red Hat Security Response Team. http://www.linuxsecurity.com/content/view/138356 * RedHat: Moderate: net-snmp security update (Jun 10) --------------------------------------------------- Updated net-snmp packages that fix a security issue are now available for Red Hat Enterprise Linux 3, 4, and 5.

(CVE-2008-1379) http://www.linuxsecurity.com/content/view/138620 * Ubuntu: openssl-blacklist update (Jun 12) ------------------------------------------ USN-612-3 addressed a weakness in OpenSSL certificate and key generation in OpenVPN by introducing openssl-blacklist to aid in detecting vulnerable private keys. This update enhances the openssl-vulnkey tool to check Certificate Signing Requests, accept input from STDIN, and check moduli without a certificate. It was also discovered that additional moduli are vulnerable if generated with OpenSSL 0.9.8g or higher. While it is believed that there are few of these vulnerable moduli in use, this update includes updated RSA-1024 and RSA-2048 blacklists. RSA-512 blacklists are also included in the new openssl-blacklist-extra package. http://www.linuxsecurity.com/content/view/138529 * Ubuntu: OpenVPN regression (Jun 12) ------------------------------------ USN-612-3 addressed a weakness in OpenSSL certificate and key generation in OpenVPN by adding checks for vulnerable certificates and keys to OpenVPN. A regression was introduced in OpenVPN when using TLS with password protected certificates which caused OpenVPN to not start when used with applications such as NetworkManager. http://www.linuxsecurity.com/content/view/138530 * Ubuntu: Evolution vulnerabilities (Jun 6) ------------------------------------------ Alin Rad Pop of Secunia Research discovered that Evolution did not properly validate timezone data when processing iCalendar attachments. If a user disabled the ITip Formatter plugin and viewed a crafted iCalendar attachment, an attacker could cause a denial of service or possibly execute code with user privileges. Note that the ITip Formatter plugin is enabled by default in Ubuntu.
