CVE-2026-3381 Details
Description
Compress::Raw::Zlib versions through 2.219 for Perl use potentially insecure versions of zlib. Compress::Raw::Zlib includes a copy of the zlib library. Compress::Raw::Zlib version 2.220 includes zlib 1.3.2, which addresses findings fron the 7ASecurity audit of zlib. The includes fixs for CVE-2026-27171.
A vulnerability exists in Compress::Raw::Zlib versions prior to 2.220, where the library uses potentially insecure versions of zlib. This issue arises because Compress::Raw::Zlib includes its own copy of the zlib library, which in versions prior to 2.220, may not have addressed certain security concerns. Notably, zlib version 1.2.11, which is included in earlier releases of Compress::Raw::Zlib, has known vulnerabilities that could be exploited to cause a denial of service by manipulating the CRC32 checksum calculations. In contrast, Compress::Raw::Zlib version 2.220 updates to zlib 1.3.2, which rectifies these vulnerabilities and is considered secure.
Users can upgrade to Compress::Raw::Zlib version 2.220 or later, which includes the secure version of zlib. Instructions for updating can be found on MetaCPAN.
