Debian Security Advisory DSA 2926-1 (linux - security update)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leaks or privilege escalation: CVE-2014-0196 Jiri Slaby discovered a race condition in the pty layer, which could lead to denial of service or privilege escalation. CVE-2014-1737 /...

UBUNTU-CVE-2014-3230

The libwww-perl LWP::Protocol::https module 6.04 through 6.06 for Perl, when using IO::Socket::SSL as the SSL socket class, allows attackers to disable server certificate validation via the 1 HTTPSCADIR or 2 HTTPSCAFILE environment variable...

DEBIAN-CVE-2014-0198

The dossl3write function in s3pkt.c in OpenSSL 1.x through 1.0.1g, when SSLMODERELEASEBUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service NULL pointer dereference and application crash via vectors...

CVE-2014-2014

imapsync before 1.584, when running with the --tls option, attempts a cleartext login when a certificate verification failure occurs, which allows remote attackers to obtain credentials by sniffing the network...

SSL/TLS CRIME attack against HTTPS

The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt, and other products, can encrypt compressed data without properly obfuscating the length of the unencrypted data, which allows man-in-the-middle attackers to obtain plaintext HTTP headers by observing length differenc...

SSL/TLS: CBC padding timing attack (lucky-13)

The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct...

OpenJDK: TLS/SSL handshake timing issues (JSSE, 8023069)

Unspecified vulnerability in Oracle Java SE 5.0u55, 6u65, and 7u45; JRockit R27.7.7 and R28.2.9; Java SE Embedded 7u45; and OpenJDK 7 allows remote attackers to affect confidentiality and integrity via vectors related to JSSE. NOTE: the previous information is from the January 2014 CPU. Oracle ha...

ALPINE-CVE-2014-0139

cURL and libcurl 7.1 before 7.36.0, when using the OpenSSL, axtls, qsossl or gskit libraries for TLS, recognize a wildcard IP address in the subject's Common Name CN field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certifica...

bouncycastle: TLS CBC padding timing attack

It was discovered that bouncycastle leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle...

InVision: TLS Renegotiation and Denial of Service Attacks on InVision.

Hi, I found a Bug in your website.It's a TLS Renegotiation and Denial of Service Attacks. Description:- A group of hackers known as THC The Hacker's Choice last week released an interesting DoS tool that works at the SSL/TLS layer. The tool is exploiting the fact that, when a new SSL connection i...

OpenSSL Heartbeat Extension Vulnerability in Multiple Cisco Products

Multiple Cisco products incorporate a version of the OpenSSL package affected by a vulnerability that could allow an unauthenticated, remote attacker to retrieve memory in chunks of 64 kilobytes from a connected client or server. The vulnerability is due to a missing bounds check in the handling ...

HackerOne: (lack of) smtp transport layer security

Hi, It appears that email messages from the platform are sent via plain SMTP even though the receiving MX supports ESMTPS the use of ESMTP when STARTTLS is also successfully negotiated to provide a strong transport encryption layer. This allows for eavesdropping along the path between the...

openssl: information disclosure in handling of TLS heartbeat extension packets

An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server...

Cisco IOS Software Multiple Network Address Translation (NAT) Denial of Service Vulnerabilities (cisco-sa-20140326-nat)

According to its self-reported version, the version of Cisco IOS running on the remote host is affected by multiple denial of service vulnerabilities in the Network Address Translation NAT implementation : - An issue exists in the TCP Input module due to the improper handling of certain sequences...
