perl-MDK-Common 1.1.11 and 1.1.24, 1.2.9 through 1.2.14, and possibly other versions, in Mandriva Linux does not properly handle strings when writing them to configuration files, which allows attackers to gain privileges via "special characters" in unspecified vectors.

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.

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.
