| CVE-2002-0059 | Cri | 0.66 | 9.8 | 0.29 | Mar 15, 2002 | The decompression algorithm in zlib 1.1.3 and earlier, as used in many different utilities and packages, causes inflateEnd to release certain memory more than once (a "double free"), which may allow local and remote attackers to execute arbitrary code via a block of malformed compression data. | |
| CVE-2003-0107 | 0.06 | — | 0.36 | Mar 7, 2003 | Buffer overflow in the gzprintf function in zlib 1.1.4, when zlib is compiled without vsnprintf or when long inputs are truncated using vsnprintf, allows attackers to cause a denial of service or possibly execute arbitrary code. | ||
| CVE-2005-2096 | 0.03 | — | 0.43 | Jul 6, 2005 | zlib 1.2 and later versions allows remote attackers to cause a denial of service (crash) via a crafted compressed stream with an incomplete code description of a length greater than 1, which leads to a buffer overflow, as demonstrated using a crafted PNG file. | ||
| CVE-2005-1849 | 0.01 | — | 0.08 | Jul 26, 2005 | inftrees.h in zlib 1.2.2 allows remote attackers to cause a denial of service (application crash) via an invalid file that causes a large dynamic tree to be produced. | ||
| CVE-2026-27171 | 0.00 | — | 0.00 | Feb 18, 2026 | zlib before 1.3.2 allows CPU consumption via crc32_combine64 and crc32_combine_gen64 because x2nmodp can do right shifts within a loop that has no termination condition. | ||
| CVE-2004-0797 | 0.00 | — | 0.02 | Oct 20, 2004 | The error handling in the (1) inflate and (2) inflateBack functions in ZLib compression library 1.2.x allows local users to cause a denial of service (application crash). |
