From 532d936be80c742d0746045d8396909822416eb5 Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Thu, 27 Jan 2005 01:49:23 +0000 Subject: [PATCH] Check for errors from EVP_VerifyInit_ex(), or EVP_VerifyUpdate might cause a segfault... This was uncovered because EVP_VerifyInit() may fail in FIPS mode if the wrong algorithm is chosen... --- crypto/asn1/a_verify.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/crypto/asn1/a_verify.c b/crypto/asn1/a_verify.c index da2a0a6d69..b91678a9f6 100644 --- a/crypto/asn1/a_verify.c +++ b/crypto/asn1/a_verify.c @@ -150,7 +150,12 @@ int ASN1_item_verify(const ASN1_ITEM *it, X509_ALGOR *a, ASN1_BIT_STRING *signat goto err; } - EVP_VerifyInit_ex(&ctx,type, NULL); + if (!EVP_VerifyInit_ex(&ctx,type, NULL)) + { + ASN1err(ASN1_F_ASN1_VERIFY,ERR_R_EVP_LIB); + ret=0; + goto err; + } EVP_VerifyUpdate(&ctx,(unsigned char *)buf_in,inl); OPENSSL_cleanse(buf_in,(unsigned int)inl); -- 2.25.1
