CVE Severity Published▾ Status Exploitation Description
CVE-2026-27171 Medium 2026-02-18 Not applicable Proof of concept only 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-2026-22184 Medium 2026-01-07 Not applicable Proof of concept only zlib versions up to and including 1.3.1.2 include a global buffer overflow in the untgz utility located under contrib/untgz. The vulnerability is limited to the standalone demonstration utility and does not affect the core zlib compression library. The flaw occurs when a user executes the untgz command with an excessively long archive name supplied via the command line, leading to an out-of-bounds write in a fixed-size global buffer.
CVE-2015-1191 Medium 2015-01-21 Not applicable No public exploit Multiple directory traversal vulnerabilities in pigz 2.3.1 allow remote attackers to write to arbitrary files via a (1) full pathname or (2) .. (dot dot) in an archive.
CVE-2013-0296 Medium 2014-04-27 Not applicable No public exploit Race condition in pigz before 2.2.5 uses permissions derived from the umask when compressing a file before setting that file's permissions to match those of the original file, which might allow local users to bypass intended access permissions while compression is occurring.
CVE-2005-1849 Medium 2005-07-26 Not applicable No public exploit 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.
