CVE-2009-0590 2 Debian, Openssl 2 Debian Linux, Openssl 2025-04-09 5.0 MEDIUM N/A
The ASN1_STRING_print_ex function in OpenSSL before 0.9.8k allows remote attackers to cause a denial of service (invalid memory access and application crash) via vectors that trigger printing of a (1) BMPString or (2) UniversalString with an invalid encoded length.
CVE-2008-0166 3 Canonical, Debian, Openssl 3 Ubuntu Linux, Debian Linux, Openssl 2025-04-09 7.8 HIGH 7.5 HIGH
OpenSSL 0.9.8c-1 up to versions before 0.9.8g-9 on Debian-based operating systems uses a random number generator that generates predictable numbers, which makes it easier for remote attackers to conduct brute force guessing attacks against cryptographic keys.
CVE-2009-1390 3 Gnu, Mutt, Openssl 3 Gnutls, Mutt, Openssl 2025-04-09 6.8 MEDIUM N/A
Mutt 1.5.19, when linked against (1) OpenSSL (mutt_ssl.c) or (2) GnuTLS (mutt_ssl_gnutls.c), allows connections when only one TLS certificate in the chain is accepted instead of verifying the entire chain, which allows remote attackers to spoof trusted servers via a man-in-the-middle attack.
CVE-2009-2409 3 Gnu, Mozilla, Openssl 3 Gnutls, Network Security Services, Openssl 2025-04-09 5.1 MEDIUM N/A
The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large.
CVE-2007-5135 1 Openssl 1 Openssl 2025-04-09 6.8 MEDIUM N/A
Off-by-one error in the SSL_get_shared_ciphers function in OpenSSL 0.9.7 up to 0.9.7l, and 0.9.8 up to 0.9.8f, might allow remote attackers to execute arbitrary code via a crafted packet that triggers a one-byte buffer underflow. NOTE: this issue was introduced as a result of a fix for CVE-2006-3738. As of 20071012, it is unknown whether code execution is possible.
CVE-2003-0131 1 Openssl 1 Openssl 2025-04-03 7.5 HIGH N/A
The SSL and TLS components for OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a allow remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack that uses a large number of SSL or TLS connections using PKCS #1 v1.5 padding that cause OpenSSL to leak information regarding the relationship between ciphertext and the associated plaintext, aka the "Klima-Pokorny-Rosa attack."
CVE-2003-0545 1 Openssl 1 Openssl 2025-04-03 10.0 HIGH 9.8 CRITICAL
Double free vulnerability in OpenSSL 0.9.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an SSL client certificate with a certain invalid ASN.1 encoding.
CVE-2005-1797 1 Openssl 1 Openssl 2025-04-03 5.1 MEDIUM N/A
The design of Advanced Encryption Standard (AES), aka Rijndael, allows remote attackers to recover AES keys via timing attacks on S-box lookups, which are difficult to perform in constant time in AES implementations.
CVE-2002-0656 3 Apple, Openssl, Oracle 5 Mac Os X, Openssl, Application Server and 2 more 2025-04-03 7.5 HIGH N/A
Buffer overflows in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allow remote attackers to execute arbitrary code via (1) a large client master key in SSL2 or (2) a large session ID in SSL3.
CVE-2002-1568 1 Openssl 1 Openssl 2025-04-03 5.0 MEDIUM N/A
OpenSSL 0.9.6e uses assertions when detecting buffer overflow attacks instead of less severe mechanisms, which allows remote attackers to cause a denial of service (crash) via certain messages that cause OpenSSL to abort from a failed assertion, as demonstrated using SSLv2 CLIENT_MASTER_KEY messages, which are not properly handled in s2_srvr.c.
CVE-2003-0544 1 Openssl 1 Openssl 2025-04-03 5.0 MEDIUM N/A
OpenSSL 0.9.6 and 0.9.7 does not properly track the number of characters in certain ASN.1 inputs, which allows remote attackers to cause a denial of service (crash) via an SSL client certificate that causes OpenSSL to read past the end of a buffer when the long form is used.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2025-04-03 5.0 MEDIUM 7.5 HIGH
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
CVE-2003-0543 1 Openssl 1 Openssl 2025-04-03 5.0 MEDIUM N/A
Integer overflow in OpenSSL 0.9.6 and 0.9.7 allows remote attackers to cause a denial of service (crash) via an SSL client certificate with certain ASN.1 tag values.
CVE-1999-0428 1 Openssl 1 Openssl 2025-04-03 7.5 HIGH N/A
OpenSSL and SSLeay allow remote attackers to reuse SSL sessions and bypass access controls.
CVE-2001-1141 2 Openssl, Ssleay 2 Openssl, Ssleay 2025-04-03 5.0 MEDIUM N/A
The Pseudo-Random Number Generator (PRNG) in SSLeay and OpenSSL before 0.9.6b allows attackers to use the output of small PRNG requests to determine the internal state information, which could be used by attackers to predict future pseudo-random numbers.
CVE-2003-0078 3 Freebsd, Openbsd, Openssl 3 Freebsd, Openbsd, Openssl 2025-04-03 5.0 MEDIUM N/A
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
CVE-2006-4339 1 Openssl 1 Openssl 2025-04-03 4.3 MEDIUM N/A
OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents OpenSSL from correctly verifying X.509 and other certificates that use PKCS #1.
CVE-2002-0657 1 Openssl 1 Openssl 2025-04-03 7.5 HIGH N/A
Buffer overflow in OpenSSL 0.9.7 before 0.9.7-beta3, with Kerberos enabled, allows attackers to execute arbitrary code via a long master key.
CVE-2002-0659 3 Apple, Openssl, Oracle 5 Mac Os X, Openssl, Application Server and 2 more 2025-04-03 5.0 MEDIUM N/A
The ASN1 library in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allows remote attackers to cause a denial of service via invalid encodings.
CVE-2003-0147 3 Openpkg, Openssl, Stunnel 3 Openpkg, Openssl, Stunnel 2025-04-03 5.0 MEDIUM N/A
OpenSSL does not use RSA blinding by default, which allows local and remote attackers to obtain the server's private key by determining factors using timing differences on (1) the number of extra reductions during Montgomery reduction, and (2) the use of different integer multiplication algorithms ("Karatsuba" and normal).
