| 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-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-2009-3766 | 2 Mutt, Openssl | 2 Mutt, Openssl | 2025-04-09 | N/A |
| mutt_ssl.c in mutt 1.5.16 and other versions before 1.5.19, when OpenSSL is used, does not verify the domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. | ||||
| CVE-2009-3767 | 5 Apple, Fedoraproject, Openldap and 2 more | 6 Mac Os X, Fedora, Openldap and 3 more | 2025-04-09 | N/A |
| libraries/libldap/tls_o.c in OpenLDAP 2.2 and 2.4, and possibly other versions, 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-2009-4355 | 2 Openssl, Redhat | 3 Openssl, Enterprise Linux, Openssl | 2025-04-09 | N/A |
| Memory leak in the zlib_stateful_finish function in crypto/comp/c_zlib.c in OpenSSL 0.9.8l and earlier and 1.0.0 Beta through Beta 4 allows remote attackers to cause a denial of service (memory consumption) via vectors that trigger incorrect calls to the CRYPTO_cleanup_all_ex_data function, as demonstrated by use of SSLv3 and PHP with the Apache HTTP Server, a related issue to CVE-2008-1678. | ||||
| CVE-2004-0975 | 4 Gentoo, Mandrakesoft, Openssl and 1 more | 6 Linux, Mandrake Linux, Mandrake Linux Corporate Server and 3 more | 2025-04-03 | N/A |
| The der_chop script in the openssl package in Trustix Secure Linux 1.5 through 2.1 and other operating systems allows local users to overwrite files via a symlink attack on temporary files. | ||||
| 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-2006-4339 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Network Satellite and 1 more | 2025-04-03 | 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-2005-2969 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Network Satellite and 1 more | 2025-04-03 | N/A |
| The SSL/TLS server implementation in OpenSSL 0.9.7 before 0.9.7h and 0.9.8 before 0.9.8a, when using the SSL_OP_MSIE_SSLV2_RSA_PADDING option, disables a verification step that is required for preventing protocol version rollback attacks, which allows remote attackers to force a client and server to use a weaker protocol than needed via a man-in-the-middle attack. | ||||
| CVE-2005-2946 | 2 Canonical, Openssl | 2 Ubuntu Linux, Openssl | 2025-04-03 | 7.5 High |
| The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature. | ||||
| CVE-2005-1797 | 1 Openssl | 1 Openssl | 2025-04-03 | 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-2000-0535 | 2 Freebsd, Openssl | 2 Freebsd, Openssl | 2025-04-03 | N/A |
| OpenSSL 0.9.4 and OpenSSH for FreeBSD do not properly check for the existence of the /dev/random or /dev/urandom devices, which are absent on FreeBSD Alpha systems, which causes them to produce weak keys which may be more easily broken. | ||||
| CVE-2001-1141 | 2 Openssl, Ssleay | 2 Openssl, Ssleay | 2025-04-03 | 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-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. | ||||
| CVE-2002-0656 | 4 Apple, Openssl, Oracle and 1 more | 8 Mac Os X, Openssl, Application Server and 5 more | 2025-04-03 | 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-2002-0657 | 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-2002-0659 | 4 Apple, Openssl, Oracle and 1 more | 8 Mac Os X, Openssl, Application Server and 5 more | 2025-04-03 | 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-2002-1568 | 2 Openssl, Redhat | 2 Openssl, Enterprise Linux | 2025-04-03 | 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-2003-0078 | 4 Freebsd, Openbsd, Openssl and 1 more | 6 Freebsd, Openbsd, Openssl and 3 more | 2025-04-03 | 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-2003-0131 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Linux and 1 more | 2025-04-03 | 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." | ||||
