CVE-2011-1473 1 Openssl 1 Openssl 2025-04-11 N/A
OpenSSL before 0.9.8l, and 0.9.8m through 1.x, does not properly restrict client-initiated renegotiation within the SSL and TLS protocols, which might make it easier for remote attackers to cause a denial of service (CPU consumption) by performing many renegotiations within a single connection, a different vulnerability than CVE-2011-5094. NOTE: it can also be argued that it is the responsibility of server deployments, not a security library, to prevent or limit renegotiation when it is inappropriate within a specific environment
CVE-2011-5095 1 Openssl 1 Openssl 2025-04-11 N/A
The Diffie-Hellman key-exchange implementation in OpenSSL 0.9.8, when FIPS mode is enabled, does not properly validate a public parameter, which makes it easier for man-in-the-middle attackers to obtain the shared secret key by modifying network traffic, a related issue to CVE-2011-1923.
CVE-2012-0027 1 Openssl 1 Openssl 2025-04-11 N/A
The GOST ENGINE in OpenSSL before 1.0.0f does not properly handle invalid parameters for the GOST block cipher, which allows remote attackers to cause a denial of service (daemon crash) via crafted data from a TLS client.
CVE-2013-6449 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-11 N/A
The ssl_get_algorithm2 function in ssl/s3_lib.c in OpenSSL before 1.0.2 obtains a certain version number from an incorrect data structure, which allows remote attackers to cause a denial of service (daemon crash) via crafted traffic from a TLS 1.2 client.
CVE-2012-1165 2 Openssl, Redhat 4 Openssl, Enterprise Linux, Jboss Enterprise Application Platform and 1 more 2025-04-11 N/A
The mime_param_cmp function in crypto/asn1/asn_mime.c in OpenSSL before 0.9.8u and 1.x before 1.0.0h allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted S/MIME message, a different vulnerability than CVE-2006-7250.
CVE-2007-5135 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-09 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-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-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-2009-1377 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-09 N/A
The dtls1_buffer_record function in ssl/d1_pkt.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote attackers to cause a denial of service (memory consumption) via a large series of "future epoch" DTLS records that are buffered in a queue, aka "DTLS record buffer limitation bug."
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-2008-0166 3 Canonical, Debian, Openssl 3 Ubuntu Linux, Debian Linux, Openssl 2025-04-09 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-2009-1386 3 Canonical, Openssl, Redhat 4 Ubuntu Linux, Openssl, Enterprise Linux and 1 more 2025-04-09 N/A
ssl/s3_pkt.c in OpenSSL before 0.9.8i allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a DTLS ChangeCipherSpec packet that occurs before ClientHello.
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-2006-2937 2 Openssl, Redhat 3 Openssl, Enterprise Linux, Network Satellite 2025-04-09 N/A
OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d allows remote attackers to cause a denial of service (infinite loop and memory consumption) via malformed ASN.1 structures that trigger an improperly handled error condition.
CVE-2009-1378 3 Canonical, Openssl, Redhat 3 Ubuntu Linux, Openssl, Enterprise Linux 2025-04-09 N/A
Multiple memory leaks in the dtls1_process_out_of_seq_message function in ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote attackers to cause a denial of service (memory consumption) via DTLS records that (1) are duplicates or (2) have sequence numbers much greater than current sequence numbers, aka "DTLS fragment handling memory leak."
CVE-2009-1379 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-09 N/A
Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote attackers to cause a denial of service (openssl s_client crash) and possibly have unspecified other impact via a DTLS packet, as demonstrated by a packet from a server that uses a crafted server certificate.
CVE-2007-3108 2 Openssl, Redhat 2 Openssl, Enterprise Linux 2025-04-09 N/A
The BN_from_montgomery function in crypto/bn/bn_mont.c in OpenSSL 0.9.8e and earlier does not properly perform Montgomery multiplication, which might allow local users to conduct a side-channel attack and retrieve RSA private keys.
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-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-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.
