CRIME Attack Uses Compression Ratio of TLS Requests as Side Channel to Hijack Secure Sessions

The new attack on TLS developed by researchers Juliano Rizzo and Thai Duong takes advantage of an information leak in the compression ratio of TLS requests as a side channel to enable them to decrypt the requests made by the client to the server. This, in turn, allows them to grab the user’s logi...

CVE-2012-3519

routerlist.c in Tor before 0.2.2.38 uses a different amount of time for relay-list iteration depending on which relay is chosen, which might allow remote attackers to obtain sensitive information about relay selection via a timing side-channel attack...

CVE-2012-3519

CVE-2012-3519 affects Tor; routerlist.c in Tor before 0.2.2.38 uses different timing for relay-list iteration, enabling a timing side-channel to leak information about relay selection. Public discussion items in Debian/OSS advisories confirm the vulnerability and that the OpenBSD/OpenSSL-style fi...

Scientific Linux Security Update : openssl on SL4.x i386/x86_64

A flaw was found in the SSLgetsharedciphers utility function. An attacker could send a list of ciphers to an application that used this function and overrun a buffer by a single byte CVE-2007-5135. Few applications make use of this vulnerable function and generally it is used only when applicatio...

Scientific Linux Security Update : openssl on SL5.x i386/x86_64

OpenSSL is a toolkit that implements Secure Sockets Layer SSL v2/v3 and Transport Layer Security TLS v1 protocols as well as a full-strength general purpose cryptography library. Datagram TLS DTLS is a protocol based on TLS that is capable of securing datagram transport UDP for instance. The...

SuSE 10 Security Update : GnuTLS (ZYPP Patch Number 8066)

This update of GnuTLS fixes multiple vulnerabilities : - remote attackers could cause a denial of service heap memory corruption and application crash via an issue in the asn1getlengthder function. CVE-2012-1569 - crafted GenericBlockCipher structures allow remote attackers to cause a denial of...
