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. - CVE-2021-3618: Enforced security checks against ALPACA attack PM-3322, jscSLE-23895, bsc1187686, bsc1187678. - Added hardening to systemd...

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...
