CUPS image-png.c and image-zoom.c buffer overflow
| cups-imagepng-imagezoom-bo (41832) |  High Risk |
Description:
CUPS is vulnerable to a heap-based buffer overflow, caused by an integer overflow in image-png.c and image-zoom.c. By persuading a victim to open a specially-crafted PNG file containing overly large width and height fields, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
Platforms Affected:
- Canonical, Ubuntu 6.06 LTS
- Canonical, Ubuntu 7.04
- Canonical, Ubuntu 7.10
- Debian, Debian Linux 4.0
- Easy Software Products, CUPS 1.3.7
- Gentoo, Linux
- RedHat, Enterprise Linux 3 Desktop
- RedHat, Enterprise Linux 3 AS
- RedHat, Enterprise Linux 3 ES
- RedHat, Enterprise Linux 3 WS
- RedHat, Enterprise Linux 4 ES
- RedHat, Enterprise Linux 4 Desktop
- RedHat, Enterprise Linux 4 AS
- RedHat, Enterprise Linux 4 WS
- RedHat, Enterprise Linux 5
- RedHat, Enterprise Linux 5 Client Workstation
- RedHat, Enterprise Linux 5 Client
