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