Description Agostino Sarubbo gentoo-dev 2014-12-03 15:13:31 UTC
From ${URL} :

Michal Zalewski reported [1] 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.

There has been no response upstream regarding this (it seems that unrtf is no longer being 
maintained) so there is no patch available as of yet.


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Comment 1 Hanno Böck gentoo-dev 2014-12-10 10:06:11 UTC
Good news: upstream is not dead. They released 0.21.6 which at least fixes some issues (including the two that got CVEs). Though there are more issues with unrtf.
Comment 2 Hanno Böck gentoo-dev 2014-12-22 07:01:51 UTC
Upstream now released 0.21.8 which contains many more fixes for more issues. It seems pretty robust now. Please bump.

CVE-2014-9275 (
  UnRTF allows remote attackers to cause a denial of service (out-of-bounds
  memory access and crash) and possibly execute arbitrary code via a crafted
  RTF file.

CVE-2014-9274 (
  UnRTF allows remote attackers to cause a denial of service (crash) and
  possibly execute arbitrary code as demonstrated by a file containing the
  string "{\cb-999999999".
