VMware Security Advisory - A denial of service flaw was found in the way libxml2 processes certain content. If an application that is linked against libxml2 processes malformed XML content, the XML content might cause the application to stop responding. A flaw was found in the way ucd-snmp checks an SNMPv3 packet's Keyed-Hash Message Authentication Code. An attacker could use this flaw to spoof an authenticated SNMPv3 packet. Multiple uses of uninitialized values were discovered in libtiff's Lempel-Ziv-Welch (LZW) compression algorithm decoder. An attacker could create a carefully crafted LZW-encoded TIFF file that would cause an application linked with libtiff to crash or, possibly, execute arbitrary code.
