Descriptions
The crc32_big function in crc32.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving big-endian CRC calculation.
La función crc32_big en crc32.c in zlib 1.2.8 podría permitir que atacantes dependientes del contexto causen impactos no especificados mediante vectores que implican cálculos CRC big-endian.
It was discovered that rsync incorrectly handled pointer arithmetic in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code. It was discovered that rsync incorrectly handled vectors involving left shifts of negative integers in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
