CVE-2009-1386 3 Canonical, Openssl, Redhat 3 Ubuntu Linux, Openssl, Openssl 2024-11-21 5.0 MEDIUM 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-2009-1379 1 Openssl 1 Openssl 2024-11-21 5.0 MEDIUM 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-2009-1378 2 Canonical, Openssl 2 Ubuntu Linux, Openssl 2024-11-21 5.0 MEDIUM 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-2009-1377 1 Openssl 1 Openssl 2024-11-21 5.0 MEDIUM 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-2009-0789 1 Openssl 1 Openssl 2024-11-21 5.0 MEDIUM 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-2009-0653 1 Openssl 1 Openssl 2024-11-21 7.5 HIGH N/A
OpenSSL, probably 0.9.6, does not verify the Basic Constraints for an intermediate CA-signed certificate, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack, a related issue to CVE-2002-0970.
CVE-2009-0591 1 Openssl 1 Openssl 2024-11-21 2.6 LOW 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-2009-0590 2 Debian, Openssl 2 Debian Linux, Openssl 2024-11-21 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-2008-7270 1 Openssl 1 Openssl 2024-11-21 4.3 MEDIUM N/A
OpenSSL before 0.9.8j, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the use of a disabled cipher via vectors involving sniffing network traffic to discover a session identifier, a different vulnerability than CVE-2010-4180.
CVE-2008-5077 1 Openssl 1 Openssl 2024-11-21 5.8 MEDIUM 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-2008-1678 1 Openssl 1 Openssl 2024-11-21 5.0 MEDIUM 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-2008-1672 2 Canonical, Openssl 2 Ubuntu Linux, Openssl 2024-11-21 4.3 MEDIUM 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-2008-0891 1 Openssl 1 Openssl 2024-11-21 4.3 MEDIUM 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-2008-0166 3 Canonical, Debian, Openssl 3 Ubuntu Linux, Debian Linux, Openssl 2024-11-21 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-2007-5135 1 Openssl 1 Openssl 2024-11-21 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-2007-4995 1 Openssl 1 Openssl 2024-11-21 9.3 HIGH 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-2007-3108 1 Openssl 1 Openssl 2024-11-21 1.2 LOW 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-2006-7250 1 Openssl 1 Openssl 2024-11-21 5.0 MEDIUM N/A
The mime_hdr_cmp function in crypto/asn1/asn_mime.c in OpenSSL 0.9.8t and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted S/MIME message.
CVE-2006-4343 3 Canonical, Debian, Openssl 3 Ubuntu Linux, Debian Linux, Openssl 2024-11-21 4.3 MEDIUM 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-2006-4339 1 Openssl 1 Openssl 2024-11-21 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.
