libssh2: out-of-bounds read

When negotiating a new SSH session with a remote server, one of libssh2's functions for doing the key exchange kexagreemethods was naively reading data from the incoming packet and using it without doing sufficient range checks. The SSHMSGKEXINIT packet arrives to libssh2 with a set of strings,...

Cisco IOS IKEv2 DoS (cisco-sa-20150325-ikev2)

According to its self-reported version, the Cisco IOS software running on the remote device is affected by a denial of service vulnerability in the Internet Key Exchange version 2 IKEv2 subsystem due to improper handling of specially crafted IKEv2 packets. A remote, unauthenticated attacker can...

Cisco IOS Malformed IKEv2 Message Processing Denial of Service Vulnerability (CNVD-2015-02088)

Cisco IOS is a popular Internet operating system. Cisco IOS and Cisco IOS XE have a security vulnerability that allows remote attackers to exploit the vulnerability to conduct denial-of-service attacks by sending specially crafted IKEv2 messages...

Cisco IOS Malformed IKEv2 Message Processing Denial of Service Vulnerability (CNVD-2015-02087)

Cisco IOS is a popular Internet operating system. A security vulnerability exists in Cisco IOS and Cisco IOS XE that allows remote attackers to exploit the vulnerability to conduct denial-of-service attacks by sending specially crafted IKEv2 messages over IPv4 or IPv6...

OpenSSL 'ssl3_get_client_key_exchange' function denial of service vulnerability

OpenSSL is an open source implementation of SSL used to enable strong encryption of network communications and is now widely used in a variety of web applications. A denial of service vulnerability exists in OpenSSL version 1.0.2. Due to a vulnerability within the implementation of the...

PuTTY < 0.64 Multiple Information Disclosure Vulnerabilities

The remote host has a version of PuTTY installed that is prior to 0.64. It is, therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists due to a failure to clear SSH-2 private key information from the memory during the saving or loading of key files to...

USN-2459-1 openssl vulnerabilities

Pieter Wuille discovered that OpenSSL incorrectly handled Bignum squaring. CVE-2014-3570 Markus Stenberg discovered that OpenSSL incorrectly handled certain crafted DTLS messages. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. CVE-2014-3571...

MGASA-2015-0022 Updated openssl packages fix security vulnerabilities

A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. This could lead to a Denial Of Service attack CVE-2014-3571. A memory leak can occur in the dtls1bufferrecord function under certain conditions. In particular this could occur if an...

DEBIAN-CVE-2015-0204

The ssl3getkeyexchange function in s3clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORTRSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to...
