<felix.moessbauer@siemens.com>\n\nThe EVP_DigestFinal_ex function returns 1 on success, 0 on failure.\nHowever, the caller expects < 0 as failure, success otherwise. By that,\nfailures in the HASH_final function are silently ignored.\n\nThis currently cannot be exploited, as the md_len != SHA256_HASH_LENGTH\nin cpio_utils.c catches this (the md_len stays at the initial value of\n0). We fix it by explicitly comparing the result of EVP_DigestFinal_ex\nagainst the expected values.\n\nFixes: d38d5359 (\"Prepare to use multiple crypto engines\")\nSigned-off-by: Felix Moessbauer <felix.moessbauer@siemens.com>\n---\ncrypto/swupdate_HASH_openssl.c | 4 +++-\n1 file changed, 3 insertions(+), 1 deletion(-)", "diff": "diff --git a/crypto/swupdate_HASH_openssl.c b/crypto/swupdate_HASH_openssl.c\nindex 9820b9c5..32fe8047 100644\n--- a/crypto/swupdate_HASH_openssl.c\n+++ b/crypto/swupdate_HASH_openssl.c\n@@ -87,8 +87,10 @@ static int openssl_HASH_final(void *ctx, unsigned char *md_value,\nif (!dgst)\nreturn -EFAULT;\n\n- return EVP_DigestFinal_ex (dgst->ctx, md_value, md_len);\n+ if (EVP_DigestFinal_ex (dgst->ctx, md_value, md_len) != 1)\n+ return -EIO;\n\n+ return 0;\n}\n\nstatic void openssl_HASH_cleanup(void *ctx)\n", "prefixes": [ "1/2" ] }
