That is good to hear as it touches many things. Thanks for letting me know. Job -----Original Message----- From: Tomas Mraz <tomas@xxxxxxxxxxx> Sent: Monday, October 24, 2022 1:58 AM To: Job Cacka <job@xxxxxxxxx>; openssl-users@xxxxxxxxxxx Subject: Re: CVE-2022-37454 SHA-3 buffer overflow The implementation of SHA-3 in OpenSSL is different from the vulnerable one. There is a plain C implementation and also assembly implementation for various CPU architectures. See crypto/sha/keccak1600.c and crypto/sha/asm/keccak1600*.pl. None of these should suffer from the CVE-2022-37454. The SHA3 low level implementation is used at various places. For example there is also the SHAKE XOF hash function implementation which uses the low level SHA3 routines. There is also an implementation of the original Keccak algorithm in the master branch.
