zoo misc.c fullpath() buffer overflow
| zoo-misc-bo (24904) |  High Risk |
Description:
zoo is vulnerable to a buffer overflow, caused by improper bounds checking by the fullpath() function in misc.c file. By creating a specially-crafted archive containing an overly long filename or pathname, a local attacker could overflow a buffer and execute arbitrary code on the system once the archive is opened by the target victim.
Platforms Affected:
- Debian, Debian Linux 3.0
- Debian, Debian Linux 3.1
- Gentoo, Linux
- linux.maruhn.com, zoo 2.10 and prior
- SuSE, SuSE Linux
Remedy:
For Debian GNU/Linux:
Refer to DSA-991-1 for patch, upgrade, or suggested workaround information. See References.
For Gentoo Linux:
Refer to GLSA 200603-05 for patch, upgrade, or suggested workaround information. See References.
For SUSE Linux:
Refer to SUSE Security Summary Report SUSE-SR:2006:005 for patch, upgrade, or suggested workaround information. See References.
For other distributions:
