OpenSSL: SSLv2 doesn't block disabled ciphers

A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that were disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks...

DEBIAN-CVE-2015-3197

ssl/s2srvr.c in OpenSSL 1.0.1 before 1.0.1r and 1.0.2 before 1.0.2f does not prevent use of disabled ciphers, which makes it easier for man-in-the-middle attackers to defeat cryptographic protection mechanisms by performing computations on SSLv2 traffic, related to the getclientmasterkey and...

NTP Timestamp Bypass Vulnerability

NTP is a network protocol that synchronizes the clocks of two computers by exchanging packets. A security vulnerability in NTP allows a local attacker to perform a man-in-the-middle attack by sending packets with zero timestamps, bypassing the source timestamp restriction...

The vulnerability of the iOS operating system, which allows a perpetrator to gain access to protected information

The vulnerability of the WebKit component of the iOS operating system is related to the lack of protection for service data. Exploiting this vulnerability can allow a malicious actor, operating remotely, to gain access to protected information through a “man-in-the-middle” attack...

UBUNTU-CVE-2015-0834

The WebRTC subsystem in Mozilla Firefox before 36.0 recognizes turns: and stuns: URIs but accesses the TURN or STUN server without using TLS, which makes it easier for man-in-the-middle attackers to discover credentials by spoofing a server and completing a brute-force attack within a short time...

Blue Coat ProxyClient / Unified Agent Certificate Validation Spoofing Vulnerability

ProxyClient is Blue Coat's recently released WAN optimization software client with integrated security and control features. Blue Coat ProxyClient 3.3.3.3 and versions 3.4.4.10 prior to 3.4.x and Unified Agent prior to 4.1.3.151952 do not properly validate certain certificates, allowing a...

CVE-2014-7745

The Flight Manager aka com.flightmanager.view application 4.0 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate...

php: multiple buffer over-reads in php_parserr

Multiple buffer over-read flaws were found in the phpparserr function of PHP. A malicious DNS server or a man-in-the-middle attacker could possibly use this flaw to crash a PHP application that used the dnsgetrecord function to perform a DNS query...

DEBIAN-CVE-2013-2073

Transifex command-line client before 0.9 does not validate X.509 certificates, which allows man-in-the-middle attackers to spoof a Transifex server via an arbitrary certificate...

PYSEC-2014-72

Transifex command-line client before 0.10 does not validate X.509 certificates for data transfer connections, which allows man-in-the-middle attackers to spoof a Transifex server via an arbitrary certificate. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-2073...

jakarta-commons-httpclient: missing connection hostname check against X.509 certificate name

It was found that Apache Commons HttpClient 3.x, as used in Amazon Flexible Payments Service FPS merchant Java SDK and other products, does not verify that the server hostname matches a domain name in the subject's Common Name CN or subjectAltName field of the X.509 certificate, which allows...

CVE-2011-5095

The Diffie-Hellman key-exchange implementation in OpenSSL 0.9.8, when FIPS mode is enabled, does not properly validate a public parameter, which makes it easier for man-in-the-middle attackers to obtain the shared secret key by modifying network traffic, a related issue to CVE-2011-1923...

UBUNTU-CVE-2011-0128

WebKit, as used in Apple iTunes before 10.2 on Windows, allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service memory corruption and application crash via vectors related to iTunes Store browsing, a different vulnerability than other CVEs listed in...

WebKit, as used in Apple iTunes before 10.2 on Windows, allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service memory corruption and application crash via vectors related to iTunes Store browsing, a different vulnerability than other CVEs listed in...

firefox/nss: doesn't handle IP-based wildcards in X509 certificates safely

Mozilla Firefox before 3.5.14 and 3.6.x before 3.6.11, Thunderbird before 3.0.9 and 3.1.x before 3.1.5, and SeaMonkey before 2.0.9 recognize a wildcard IP address in the subject's Common Name field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL serve...

DEBIAN-CVE-2010-3900

Midori before 0.2.5, when WebKitGTK+ before 1.1.14 or LibSoup before 2.29.91 is used, does not verify X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary https web sites via a crafted server certificate, a related issue to CVE-2010-3312...
