Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
A flaw was reported in the TLS session ticket key construction in GnuTLS, a library implementing the TLS and SSL protocols. The flaw caused the TLS server to not securely construct a session ticket encryption key considering the application supplied secret, allowing a
Two vulnerabilities were discovered in Node.js, which could result in denial of service and potentially the execution of arbitrary code. For the stable distribution (buster), these problems have been fixed in
Multiple security issues have been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code or a timing attack on cryptographic keys.
Two vulnerabiliites have been discovered in Unbound, a recursive-only caching DNS server; a traffic amplification attack against third party authoritative name servers (NXNSAttack) and insufficient sanitisation of replies from upstream servers could result in denial of service via
Several vulnerabilities were discovered in Drupal, a fully-featured content management framework, which could result in an open redirect or cross-site scripting.
Georgi Guninski and the Qualys Research Labs discovered multiple vulnerabilities in qmail (shipped in Debian as netqmail with additional patches) which could result in the execution of arbitrary code, bypass of mail address verification and a local information leak whether a file
Two vulnerabiliites have been discovered in PDNS Recursor, a resolving name server; a traffic amplification attack against third party authoritative name servers (NXNSAttack) and insufficient validation of NXDOMAIN responses lacking an SOA.
Several vulnerabilities were discovered in the Dovecot email server, which could cause crashes in the submission, submission-login or lmtp services, resulting in denial of service.
