In ngpkt in transports/smartpkt.c in libgit2 before 0.26.6 and 0.27.x before 0.27.4, a remote attacker can send a crafted smart-protocol "ng" packet that lacks a '\0' byte to trigger an out-of-bounds read that leads to DoS...

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...
