CVE-2017-6961

There is improper sanitization of user input causing huge memory allocations, resulting in a crash.

MEDIUM 5.5EPSS 0.80%

Does this matter?

Lower severity and a low EPSS score (0.80%). Track it; it rarely justifies an emergency change on its own.

Description

An issue was discovered in apng2gif 1.7. There is improper sanitization of user input causing huge memory allocations, resulting in a crash. This is related to the read_chunk function using the pChunk->size value (within the PNG file) to determine the amount of memory to allocate.
