New libssh packages are available for Slackware 15.0 and -current to address several security issues, including potential UAF (use-after-free) vulnerabilities and memory leaks. The updated packages, version 0.11.3, address these issues and can be found on the Slackware FTP server or mirrored at additional sites listed on the project's website. Users are advised to upgrade their libssh package as root using the "upgradepkg" command with the corresponding .txz file.
