zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. zlib versiones anteriores a 1.2.12 permite la corrupción de memoria al desinflar (es decir, al comprimir) si la entrada tiene muchas coincidencias distantes An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application. • http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 http://www.openwall.com/lists/oss-security/2022/03/25/2 http://www.openwall.com/lists/oss-security/2022/03/26/1 https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf https://github.com/madler/zlib/commit/5c44459c3b28a9bd3283aaceab7c615f8020c531 https://github.com/madler/zlib/compare/v1.2.11...v1.2.12 https://github.com& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
