FEDORA-2019-9d85600fc7 created by pghmcfc a year ago for Fedora 30
stable

A vulnerability was discovered in libssh2 before 1.9.0, kex_method_diffie_hellman_group_exchange_sha256_key_exchange in kex.c has an integer overflow that could lead to an out-of-bounds write in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.

This is related to an _libssh2_check_length mistake, and is different from the various issues fixed in 1.8.1, such as CVE-2019-3855.

This update, to the latest current upstream release 1.9.0, addresses this security issue and also includes a number of other bug fixes and enhancements as described in the package changelog.
