Updated unrtf package fixes security vulnerabilities:

Michal Zalewski reported an out-of-bounds memory access vulnerability
in unrtf. Processing a malformed RTF file could lead to a segfault
while accessing a pointer that may be under the attacker’s control.
This would lead to a denial of service (application crash) or,
potentially, the execution of arbitrary code (CVE-2014-9274).

Hanno Bck also reported a number of other crashes in unrtf
(CVE-2014-9275).
