Name of the Vulnerable Software and Affected Versions apng2gif version 1.7

Description An issue was discovered where improper sanitization of user input leads to huge memory allocations, causing a crash. This issue is related to the read chunk function using the pChunk->size value within the PNG file to determine the amount of memory to allocate.

Recommendations For apng2gif version 1.7, consider restricting the input to prevent huge memory allocations until a patch is available. As a temporary workaround, limiting the pChunk->size value used by the read chunk function could help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
