Issue summary: If an application using the SSLCIPHERfind() function in a QUIC protocol client or server receives an unknown cipher suite from the peer, a NULL dereference occurs.
Impact summary: A NULL pointer dereference leads to abnormal termination of the running process causing Denial of Service.
Some applications call SSLCIPHERfind() from the clienthellocb callback on the cipher ID received from the peer. If this is done with an SSL object implementing the QUIC protocol, NULL pointer dereference will happen if the examined cipher ID is unknown or unsupported.
As it is not very common to call this function in applications using the QUIC protocol and the worst outcome is Denial of Service, the issue was assessed as Low severity.
The vulnerable code was introduced in the 3.2 version with the addition of the QUIC protocol support.
The FIPS modules in 3.6, 3.5, 3.4 and 3.3 are not affected by this issue, as the QUIC implementation is outside the OpenSSL FIPS module boundary.
OpenSSL 3.6, 3.5, 3.4 and 3.3 are vulnerable to this issue.
OpenSSL 3.0, 1.1.1 and 1.0.2 are not affected by this issue.
