CVE-2023-2283 severity moderate: SUSE including 335 source package names (1.2.3-2.2.63:libssh-config-0.9.8-150400.3.3.1, 1.2.3-2.2.63:libssh4-0.9.8-150400.3.3.1, …), 895 product×package rows across 257 product lines (Container bci/golang, Container bci/nodejs, … (257 product lines)): Fixed 602, Known Affected 195, Known Not Affected 98.
A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
