F5 Networks BIG-IP : OpenSSL vulnerability (SOL15388)

The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack. C Tenable Network Security, Inc. The descriptive text and package checks in th...

F5 Networks BIG-IP : OpenSSL vulnerability (SOL15147)

The sslgetalgorithm2 function in ssl/s3lib.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. C Tenable Network Security, Inc. The descripti...

F5 Networks BIG-IP : OpenSSL vulnerability (K15158)

The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context and cause a denial of service...

F5 Networks BIG-IP : OpenSSL vulnerability (SOL11533)

The ssl3getrecord function in ssl/s3pkt.c in OpenSSL 0.9.8f through 0.9.8m allows remote attackers to cause a denial of service crash via a malformed record in a TLS connection that triggers a NULL pointer de-reference, related to the minor version number. %NASLMINLEVEL 70300 C Tenable Network...

F5 Networks BIG-IP : OpenSSL vulnerability (K15159) (Heartbleed)

The 1 TLS and 2 DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys,...

F5 Networks BIG-IP : OpenSSL vulnerability (SOL15343)

The dtls1getmessagefragment function in d1both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service recursion and client crash via a DTLS hello message in an invalid DTLS handshake. C Tenable Network Security, Inc. The...

F5 Networks BIG-IP : OpenSSL vulnerability (K15356)

The dtls1reassemblefragment function in d1both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service buffer overflow a...

F5 Networks BIG-IP : OpenSSL vulnerability (SOL15404)

OpenSSL before 0.9.8m does not check for a NULL return value from bnwexpand function calls in 1 crypto/bn/bndiv.c, 2 crypto/bn/bngf2m.c, 3 crypto/ec/ec2smpl.c, and 4 engines/eubsec.c, which has unspecified impact and context-dependent attack vectors.

Heartbleed Exploit Linked to Community Health Data Breach

Update: The Heartbleed OpenSSL vulnerability is now the centerpiece of the Community Health Systems data breach. Dave Kennedy, CEO of security consultancy TrustedSec, said yesterday that three sources close to the CHS investigation told him that a Heartbleed exploit was the hackers’ initial way i...

CVE-2014-3509

Race condition in the sslparseserverhellotlsext function in t1lib.c in OpenSSL 1.0.0 before 1.0.0n and 1.0.1 before 1.0.1i, when multithreading and session resumption are used, allows remote SSL servers to cause a denial of service memory overwrite and client application crash or possibly have...

CVE-2014-3508

The OBJobj2txt function in crypto/objects/objdat.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i, when pretty printing is used, does not ensure the presence of '\0' characters, which allows context-dependent attackers to obtain sensitive information from process...

CVE-2014-5139

The sslsetclientdisabled function in t1lib.c in OpenSSL 1.0.1 before 1.0.1i allows remote SSL servers to cause a denial of service NULL pointer dereference and client application crash via a ServerHello message that includes an SRP ciphersuite without the required negotiation of that ciphersuite...
