A medium-severity heap buffer overflow in ImageMagick. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 1.0% (higher than 64% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
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.
