| Vetor | AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
GraphicsMagick version 1.4
Description
The issue is related to a Buffer Overflow vulnerability in the WritePCXImage function in pcx.c, which allows remote attackers to cause a denial of service via converting a crafted image file to pcx format. This can be achieved by exploiting the buffer overflow in the WritePCXImage function, potentially leading to a denial of service.
Recommendations
For GraphicsMagick version 1.4, consider disabling the WritePCXImage function in pcx.c as a temporary workaround to minimize the risk of exploitation until a patch is available. Restrict access to converting image files to pcx format to prevent potential denial of service attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
