It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-075 advisory.

- An issue was discovered in giflib through 5.1.4. DumpScreen2RGB in gif2rgb.c has a heap-based buffer over- read. (CVE-2020-23922)

- There is a heap-buffer-overflow in GIFLIB 5.2.1 function DumpScreen2RGB() in gif2rgb.c:298:45.
