Unknown vulnerability in foomatic-rip in Foomatic before 3.0.2 allows local users or remote attackers with access to CUPS to execute arbitrary commands.

The mod_dav module in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (child process crash) via a certain sequence of LOCK requests for a location that allows WebDAV authoring access.

The Portable Network Graphics library (libpng) 1.0.15 and earlier allows attackers to cause a denial of service (crash) via a malformed PNG image file that triggers an error that causes an out-of-bounds read when creating the error message.

Multiple stack-based buffer overflows in the ICQ parsing routines of the ISS Protocol Analysis Module (PAM) component, as used in various RealSecure, Proventia, and BlackICE products, allow remote attackers to execute arbitrary code via a SRV_MULTI response containing a SRV_USER_ONLINE response packet and a SRV_META_USER response packet with long (1) nickname, (2) firstname, (3) lastname, or (4) email address fields, as exploited by the Witty worm.

Heap-based buffer overflow in the ISS Protocol Analysis Module (PAM), as used in certain versions of RealSecure Network 7.0 and Server Sensor 7.0, Proventia A, G, and M Series, RealSecure Desktop 7.0 and 3.6, RealSecure Guard 3.6, RealSecure Sentry 3.6, BlackICE PC Protection 3.6, and BlackICE Server Protection 3.6, allows remote attackers to execute arbitrary code via an SMB packet containing an authentication request with a long username.

Sybergen Secure Desktop 2.1 does not properly protect against false router advertisements (ICMP type 9), which allows remote attackers to modify default routes.
