Attack profile from CVSS 3.1 · NVD. Fix status from CNA and Red Hat. Impact type from CWE-122 and the CVSS impact.
Summary
The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). This could cause impact to reliability. This flaw affects ImageMagick versions prior to 7.0.8-68.
