SUSE CVE-2019-13115

In libssh2 before 1.9.0, kexmethoddiffiehellmangroupexchangesha256keyexchange in kex.c has an integer overflow that could lead to an out-of-bounds read in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to disclose sensitive information or caus...

SUSE CVE-2019-17498

In libssh2 v1.9.0 and earlier versions, the SSHMSGDISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary out-of-bounds offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a...

SUSE CVE-2023-22742

libgit2 is a cross-platform, linkable library implementation of Git. When using an SSH remote with the optional libssh2 backend, libgit2 does not perform certificate checking by default. Prior versions of libgit2 require the caller to set the certificatecheck field of libgit2's gitremotecallbacks...

The vulnerability of the libssh2 library, which implements Git methods in C language using Libgit2, allows a attacker to perform a type of “man-in-the-middle” attack.

The vulnerability of the libssh2 library, which implements Git methods in C using Libgit2, is related to errors in verifying the cryptographic signature. Exploiting this vulnerability could allow a remote attacker to execute a “man-in-the-middle” attack...
