xzgv and zgv JPEG image parsing buffer overflow
| xzgv-jpeg-bo (25718) |  High Risk |
Description:
xzgv is vulnerable to a heap-based buffer overflow caused by improper bounds checking of JPEG images. By creating a specially-crafted JPEG image, a remote attacker could overflow a buffer and execute arbitrary code on the system, if a victim views the image within the CMYK/YCCK color space.
Consequences:
Gain Access
Remedy:
Apply the patch for this vulnerability, available from the xzgv Web page. See References.
