High

Base vector

AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: Libnsgif version 0.1.2

Description: The issue is a stack-based buffer overflow in the gif next LZW function, which can be triggered by a crafted LZW stream in a GIF file. This can cause a denial of service, resulting in an application crash, or potentially allow the execution of arbitrary code.

Recommendations: For Libnsgif version 0.1.2, consider updating to a newer version that addresses this issue, as using a crafted GIF file could lead to a denial of service or code execution. If no update is available, as a temporary workaround, consider restricting the use of GIF files or implementing additional validation on LZW streams to minimize the risk of exploitation.
