dbus-daemon in D-Bus before 1.0.3, and 1.1.x before 1.1.20, recognizes send_interface attributes in allow directives in the security policy only for fully qualified method calls, which allows local users to bypass intended access restrictions via a method call with a NULL interface.

Stack-based buffer overflow in the zseticcspace function in zicc.c in Ghostscript 8.61 and earlier allows remote attackers to execute arbitrary code via a postscript (.ps) file containing a long Range array in a .seticcspace operator.

Xdg-utils 1.0.2 and earlier allows user-assisted remote attackers to execute arbitrary commands via shell metacharacters in a URL argument to (1) xdg-open or (2) xdg-email.

The pa_drop_root function in PulseAudio 0.9.8, and a certain 0.9.9 build, does not check return values from (1) setresuid, (2) setreuid, (3) setuid, and (4) seteuid calls when attempting to drop privileges, which might allow local users to gain privileges by causing those calls to fail via attacks such as resource exhaustion.

The xmlCurrentChar function in libxml2 before 2.6.31 allows context-dependent attackers to cause a denial of service (infinite loop) via XML containing invalid UTF-8 sequences.

Buffer overflow in the polymorphic opcode support in the Regular Expression Engine (regcomp.c) in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode (UTF) characters in a regular expression.
