CVE-2015-2674

Restkit allows man-in-the-middle attackers to spoof TLS servers by leveraging use of the ssl.wrapsocket function in Python with the default CERTNONE value for the certreqs argument...

Reaching toward universal TLS SNI

The past few years have seen a dramatic increase in client support for TLS SNI a technology standard that makes HTTPS much more scaleable. While early 2014 saw fewer than 85% of HTTPS requests being sent by clients supporting TLS SNI, many Akamai customers today now see client TLS SNI usage...

CURL-CVE-2016-9952 Win CE Schannel cert wildcard matches too much

curl's TLS server certificate checks are flawed on Windows CE. This vulnerability occurs in the verify certificate function when comparing a wildcard certificate name as returned by the Windows API function CertGetNameString to the hostname used to make the connection to the server. The...

Fedora 24 : glib-networking-2.48.1-1.fc24 (2016-5e897e9b85)

Update to 2.48.1. Add patch for denial of service when TLS server sends the same self-signed certificate twice in a chain. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and...

openssl: assertion failure in SSLv2 servers

A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled...

Vulnerability in OpenSSL - DH small subgroups

Historically OpenSSL usually only ever generated DH parameters based on “safe” primes. More recently in version 1.0.2 support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support. The primes used in such files may not be “safe”. Where an application ...

This update contains mozilla-nss 3.19.2.2 and fixes the following security issue: - CVE-2015-7575: MD5 signatures accepted within TLS 1.2 ServerKeyExchange in server signature bsc959888...

Amazon Linux AMI : openssl (ALAS-2014-427)

A memory leak flaw was found in the way OpenSSL parsed the DTLS Secure Real-time Transport Protocol SRTP extension data. A remote attacker could send multiple specially crafted handshake messages to exhaust all available memory of an SSL/TLS or DTLS server. CVE-2014-3513 A memory leak flaw was...

openSUSE Security Update : libopenssl-devel (openSUSE-SU-2011:0634-1)

This update of openssl fixes a timing attack. This attack can be used to obtain the private key of a TLS server whenever ECDSA signatures are used. CVE-2011-1945: CVSS v2 Base Score: 4.3 important AV:N/AC:M/Au:N/C:P/I:N/A:N: Cryptographic Issues CWE-310 %NASLMINLEVEL 70300 C Tenable Network...

Scientific Linux Security Update : openssl on SL6.x i386/x86_64

A race condition flaw has been found in the OpenSSL TLS server extension parsing code, which could affect some multithreaded OpenSSL applications. Under certain specific conditions, it may be possible for a remote attacker to trigger this race condition and cause such an application to crash, or...

Scientific Linux Security Update : openssl on SL6.x i386/x86_64

A ciphersuite downgrade flaw was found in the OpenSSL SSL/TLS server code. A remote attacker could possibly use this flaw to change the ciphersuite associated with a cached session stored on the server, if the server enabled the SSLOPNETSCAPEREUSECIPHERCHANGEBUG option, possibly forcing the clien...

tls-nextprotoneg NSE Script

Enumerates a TLS server's supported protocols by using the next protocol negotiation extension. This works by adding the next protocol negotiation extension in the client hello packet and parsing the returned server hello's NPN extension data. For more information, see: Script Arguments...
