Description Lubomir Kundrak 2007-04-30 12:35:09 UTC
+++ This bug was initially created as a clone of Bug #238420 +++ Description of problem: There is a possible stack-based buffer overrun in function plug-ins/common/sunras.c:set_color_table() that can be exploited by an attacker to trigger execution of arbitrary code via crafted Sun RAS file. Version-Release number of selected component (if applicable): Affects: RHEL2.1 Affects: RHEL3 Affects: RHEL4 Affects: RHEL5 Affects: FC5 Affects: FC6 Steps to Reproduce: Either use the program referred to in URL to generate a POC, or use one that is attached to this bug. Additional info: Though I have reproduced a crash on all supported systems, as enumerated above, for some unknown reason gdb was detaching from the plugin run with GIMP_PLUGIN_DEBUG=sunras, so I was unable to do a depth-in investigation. I deduce, that it is a stack overflow because core dumps showed evidence of corrupt stack, with ssp glibc detects a stack smashing, and Secunia advisory also states the same: http://secunia.com/advisories/25012/?answer=57 -- Additional comment from firstname.lastname@example.org on 2007-04-30 08:32 EST -- Created an attachment (id=153788) Malformed Sun RAS file, that overflows stack in gimp's sunras plugin
Comment 1 Nils Philippsen 2007-04-30 14:28:05 UTC
fc5 -> devel
Comment 2 Nils Philippsen 2007-04-30 15:59:10 UTC
Upstream already has a fix by Sven Neumann, I've extracted that from the SVN repo and built a fixed gimp-2.2.14-2.fc7 package. Pinged rel-eng to put it into final.
Comment 3 Nils Philippsen 2007-04-30 16:51:38 UTC
Found small packaging quirk that deleted symlinks to external plugins when updated, gimp-2.2.14-3.fc7 should be fixed in that regard (which is building right now). Pinged rel-eng.
Comment 4 Nils Philippsen 2007-04-30 16:52:49 UTC
BTW: Confirmed that the patch actually fixes the bug, i.e. doesn't crash the plugin but gives a warning about "EOF encountered on reading".
Comment 5 Nils Philippsen 2007-05-01 09:10:12 UTC
Fixed the fix for the quirk mentioned in comment #3 in gimp-2.2.14-5.fc7.
Comment 6 Bug Zapper 2008-04-04 00:23:30 UTC
Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again.

Seems already fixed in Rawhide.
