Summary
libssh2 security update
Details

libssh2 is a library implementing the SSH2 protocol as defined by Internet Drafts: SECSH-TRANS(22), SECSH-USERAUTH(25), SECSH-CONNECTION(23), SECSH-ARCH(20), SECSH-FILEXFER(06)*, SECSH-DHGEX(04), and SECSH-NUMBERS(10).

Security Fix(es):

A security vulnerability has been detected in libssh2 up to 1.11.1. The impacted element is the function userauthpassword of the file src/userauth.c. Such manipulation of the argument usernamelen/password_len leads to integer overflow. The attack may be launched remotely. The name of the patch is 256d04b60d80bf1190e96b0ad1e91b2174d744b1. A patch should be applied to remediate this issue.(CVE-2026-7598)
