Description Jan Lieskovsky 2012-10-04 12:21:13 UTC
A stack-based buffer overflow flaw was found in the way FuseISO, a FUSE module to mount ISO filesystem images, performed expanding of directories portions for absolute path filename entries. A remote attacker could provide a specially-crafted ISO file that, when mounted via fuseiso tool would lead to fuseiso binary crash or, potentially, arbitrary code execution with the privileges of the user running the fuseiso executable.

Note: Since the fuseiso binary on Fedora is compiled with FORTIFY_SOURCE protection enabled, this flaw would allow an attacker to cause fuseiso binary to crash only.


This issue was discovered by Florian Weimer of Red Hat Product Security Team.

Comment 1 Jan Lieskovsky 2012-10-04 12:26:55 UTC
This issue affects the versions of the fuseiso package, as shipped with Fedora release of 16 and 17.

Comment 2 tomasz 2015-03-11 07:44:21 UTC
Debian bug #779047 brought me here: is there a PoC ISO file that causes this issue to happen?
