CVE-2015-1782

Publication date 13 March 2015

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The kex_agree_methods function in libssh2 before 1.5.0 allows remote servers to cause a denial of service (crash) or have other unspecified impact via crafted length values in an SSH_MSG_KEXINIT packet.

From the Ubuntu Security Team

It was discovered that libssh2 mishandled certain input. If libssh2 were used to connect to a malicious or compromised SSH server, the server could cause the client to crash.
