zlib 1.3.1.2 through 1.3.2 Heap Buffer Overflow via gz_vacate

zlib versions 1.3.1.2 through 1.3.2 contain a heap buffer overflow vulnerability in the gz_vacate() function when processing non-blocking gzwrite() operations with stale external buffer pointers. Attackers can trigger the overflow by calling gzprintf() or gzvprintf() after a write stall, causing an unchecked memmove() to write beyond the internal input buffer boundary.

CVE-2022-37434

zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference).

• Обновитесь до 2.0.10-4ubuntu0.1

CVE-2018-25032

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.

• Обновитесь до 2.0.10-4ubuntu0.1

CVE-2016-9843

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.

• Обновитесь до 2.0.10-4ubuntu0.2

CVE-2016-9841

inffast.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic.

• Обновитесь до 2.0.10-4ubuntu0.1

CVE-2016-9840

inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic.
