CVE-2026-50046

A use-after-free flaw was found in Unbound's DNS-over-TLS DoT forwarded query handling. A remote attacker can exploit a timing error during TLS handshake failures on a server under load to trigger a daemon crash, resulting in a Denial of Service DoS. Mitigation To mitigate this issue, avoid...

CVE-2026-16529

A signed integer overflow in the PCP pmGetPDU function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service DoS for subsequent packet reads. Mitigation To mitigate this issue,...

CVE-2026-47086

A flaw was found in cyrus-imapd. An authenticated user could exploit this vulnerability by minting a URLAUTH token through the GENURLAUTH command.
