CVE-2018-25032 is a high-severity memory corruption vulnerability affecting the zlib data compression library, which is used in various software configurations and operating systems. This issue occurs when compressing input with many distant matches and may lead to unexpected application termination or arbitrary code execution. To address this vulnerability, it is recommended to update the affected software to the latest versions.

How do I know if I'm affected?

If you're using software or an operating system that relies on the zlib library, you might be affected by the vulnerability. This issue is present in zlib versions before 1.2.12 and can cause memory corruption when compressing data with distant matches. Affected systems include certain versions of Debian Linux, Fedora, Apple macOS, Python, and MariaDB. To check if you're affected, verify the version of zlib or the software you're using and see if it falls within the vulnerable range. Keep in mind that this vulnerability might not show obvious signs or symptoms.

What should I do if I'm affected?

If you're affected by the vulnerability, it's important to update your software to the latest version. For macOS users, install Security Update 2022-004 Catalina from the Mac App Store. Fedora users can run the command su -c 'dnf upgrade --advisory FEDORA-2022-b58a85e167'. Gentoo users should use the emerge command to upgrade zlib to version 1.2.12-r3 or later. Always keep your software up-to-date to stay protected.

Is this in CISA’s Known Exploited Vulnerabilities Catalog?

The CVE-2018-25032 vulnerability is not listed in CISA's Known Exploited Vulnerabilities Catalog.
