Description Lubomir Kundrak 2007-04-30 12:32:40 UTC
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:

Upstream already has a fix by Sven Neumann, I've extracted that from the SVN
repo and I'm just building the package (with two minor, trivial packaging fixes)
locally to see that it works out.
