SUSE SLES15 Security Update : vsftpd (SUSE-SU-2022:3458-1)

The remote SUSE Linux SLES15 / SLESSAP15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2022:3458-1 advisory. - ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using...

ALPACA is an application layer protocol content confusion attack exploiting TLS servers implementing different protocols but using compatible certificates such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.

Internet Bug Bounty: Cross-protocol attack on TLS using SSLv2 (DROWN) (CVE-2016-0800)

General DROWN was responsibly disclosed to the OpenSSL team prior to the public disclosure. This OpenSSL blog post, by Viktor Dukhovni and Emilia Käsper, describes the vulnerability: https://www.openssl.org/blog/blog/2016/03/01/an-openssl-users-guide-to-drown/ This is probably a good opportunity ...

SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack ...

Important: openssl098e

Issue Overview: 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. CVE-2015-02...
