Description Huzaifa S. Sidhpurwala 2011-01-03 08:40:30 UTC

Several stack-based buffer overflows were found in the way gimp
processes plug-in configuration files. An attacker could create a
a specially-crafted plug-in configuration file and trick the local, 
unsuspecting user into opening it, which could lead to gimp to crash
the plugin or, potentially , arbitrary code execution with
the privileges of the user running the executable.

Public PoC:
http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=gimp-overflows-poc-in-cobol.cob;att=1;bug=608497

Flaw severity note:
On systems with compile time buffer checks (FORTIFY_SOURCE)
feature enabled, the impact of this flaw is mitigated to
be only crash.

Comment 2 Vincent Danen 2011-01-04 18:40:34 UTC

There are four buffer overflows here and as a result this has been given four CVE names:

http://article.gmane.org/gmane.comp.security.oss.general/4025

CVE-2010-4540 gimp LIGHTING EFFECTS > LIGHT plugin stack buffer overflow
CVE-2010-4541 gimp SPHERE DESIGNER plugin stack buffer overflow
CVE-2010-4542 gimp GFIG plugin stack buffer overflow
CVE-2010-4543 gimp heap overflow read_channel_data() in file-psp.c

If we need to, we can split these into separate bugs (but I think that when we fix them, we would do them all at once, so only split this if any of these don't affect something we ship).

This bug is now dedicated to CVE-2010-4540 issue:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-4540

Stack-based buffer overflow in the load_preset_response function
in plug-ins/lighting/lighting-ui.c in the "LIGHTING EFFECTS > LIGHT"
plugin in GIMP 2.6.11 allows user-assisted remote attackers to cause
a denial of service (application crash) or possibly execute arbitrary
code via a long Position field in a plugin configuration file. NOTE:
it may be uncommon to obtain a GIMP plugin configuration file from
an untrusted source that is separate from the distribution of the
plugin itself. NOTE: some of these details are obtained from third
party information.
