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-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-2009-3765 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-2009-0591 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-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-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-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-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-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-2009-3555 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-2009-1377 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-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-2009-2409 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-2003-0147 4 Openpkg, Openssl, Redhat and 1 more 6 Openpkg, Openssl, Enterprise Linux and 3 more 2025-04-03 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).
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-2005-2969 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-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-2002-1568 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-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-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.
