Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Improper handling of zero-size or invalid GIF frame allocations in reallocarray leading to potential double-free or use-after-free conditions. These vulnerabilities are exemplified by CVE-2019-11932.
Out-of-bounds Write: Bypassed safety checks due to positive/negative dimension overflows and improper coordinate mapping against original screen dimensions during parsing in DGifGetImageDesc.
Use After Free: Failing to safely nullify and free the rasterBits pointer upon failure to read frame headers, allowing downstream code to read or write to stale memory.
