CVE-2008-5077 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-09 N/A
OpenSSL 0.9.8i and earlier does not properly check the return value from the EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys.
CVE-2006-2940 2 Openssl, Redhat 3 Openssl, Enterprise Linux, Network Satellite 2025-04-09 N/A
OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial of service (CPU consumption) via parasitic public keys with large (1) "public exponent" or (2) "public modulus" values in X.509 certificates that require extra time to process when using RSA signature verification.
CVE-2009-3555 9 Apache, Canonical, Debian and 6 more 15 Http Server, Ubuntu Linux, Debian Linux and 12 more 2025-04-09 N/A
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue.
CVE-2007-4995 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-09 N/A
Off-by-one error in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8f allows remote attackers to execute arbitrary code via unspecified vectors.
CVE-2009-0789 1 Openssl 1 Openssl 2025-04-09 N/A
OpenSSL before 0.9.8k on WIN64 and certain other platforms does not properly handle a malformed ASN.1 structure, which allows remote attackers to cause a denial of service (invalid memory access and application crash) by placing this structure in the public key of a certificate, as demonstrated by an RSA public key.
CVE-2009-3765 2 Mutt, Openssl 2 Mutt, Openssl 2025-04-09 N/A
mutt_ssl.c in mutt 1.5.19 and 1.5.20, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
CVE-2009-1387 3 Canonical, Openssl, Redhat 4 Ubuntu Linux, Openssl, Enterprise Linux and 1 more 2025-04-09 N/A
The dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL before 1.0.0 Beta 2 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence DTLS handshake message, related to a "fragment bug."
CVE-2008-1672 2 Canonical, Openssl 2 Ubuntu Linux, Openssl 2025-04-09 N/A
OpenSSL 0.9.8f and 0.9.8g allows remote attackers to cause a denial of service (crash) via a TLS handshake that omits the Server Key Exchange message and uses "particular cipher suites," which triggers a NULL pointer dereference.
CVE-2006-3738 2 Openssl, Redhat 3 Openssl, Enterprise Linux, Network Satellite 2025-04-09 N/A
Buffer overflow in the SSL_get_shared_ciphers function in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions has unspecified impact and remote attack vectors involving a long list of ciphers.
CVE-2009-0591 1 Openssl 1 Openssl 2025-04-09 N/A
The CMS_verify function in OpenSSL 0.9.8h through 0.9.8j, when CMS is enabled, does not properly handle errors associated with malformed signed attributes, which allows remote attackers to repudiate a signature that originally appeared to be valid but was actually invalid.
CVE-2006-4343 4 Canonical, Debian, Openssl and 1 more 5 Ubuntu Linux, Debian Linux, Openssl and 2 more 2025-04-09 N/A
The get_server_hello function in the SSLv2 client code in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows remote servers to cause a denial of service (client crash) via unknown vectors that trigger a null pointer dereference.
CVE-2009-2409 4 Gnu, Mozilla, Openssl and 1 more 7 Gnutls, Network Security Services, Openssl and 4 more 2025-04-09 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-2008-1678 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-09 N/A
Memory leak in the zlib_stateful_init function in crypto/comp/c_zlib.c in libssl in OpenSSL 0.9.8f through 0.9.8h allows remote attackers to cause a denial of service (memory consumption) via multiple calls, as demonstrated by initial SSL client handshakes to the Apache HTTP Server mod_ssl that specify a compression algorithm.
CVE-2009-1390 3 Gnu, Mutt, Openssl 3 Gnutls, Mutt, Openssl 2025-04-09 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-2008-0891 1 Openssl 1 Openssl 2025-04-09 N/A
Double free vulnerability in OpenSSL 0.9.8f and 0.9.8g, when the TLS server name extensions are enabled, allows remote attackers to cause a denial of service (crash) via a malformed Client Hello packet. NOTE: some of these details are obtained from third party information.
CVE-2003-0544 2 Openssl, Redhat 4 Openssl, Enterprise Linux, Linux and 1 more 2025-04-03 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-1999-0428 1 Openssl 1 Openssl 2025-04-03 6.5 Medium
OpenSSL and SSLeay allow remote attackers to reuse SSL sessions and bypass access controls.
CVE-2003-0851 3 Cisco, Openssl, Redhat 7 Css11000 Content Services Switch, Ios, Pix Firewall and 4 more 2025-04-03 N/A
OpenSSL 0.9.6k allows remote attackers to cause a denial of service (crash via large recursion) via malformed ASN.1 sequences.
CVE-2002-0657 1 Openssl 1 Openssl 2025-04-03 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-2002-0655 4 Apple, Openssl, Oracle and 1 more 8 Mac Os X, Openssl, Application Server and 5 more 2025-04-03 N/A
OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, does not properly handle ASCII representations of integers on 64 bit platforms, which could allow attackers to cause a denial of service and possibly execute arbitrary code.
