| 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
ImageMagick versions prior to 7.0.8-68
Description
The issue is related to the PALM image coder in ImageMagick, which makes an improper call to
AcquireQuantumMemory() in the WritePALMImage() routine due to an offset of 256. This can cause an out-of-bounds read later in the routine, potentially impacting reliability. The flaw allows a remote attacker to cause a denial of service by exploiting the out-of-bounds read in the buffer data.Recommendations
For versions prior to 7.0.8-68, update to version 7.0.8-68 or later to resolve the issue. As a temporary workaround, consider restricting access to the
WritePALMImage() routine in the coders/palm.c file until a patch is applied. Additionally, be cautious when handling PALM image files to minimize the risk of exploitation.Exploit
