Denial of TLS certificate issuance and renewal in Progressive Robot hMailServer 6.0.0 through 6.3.6 stems from the ACME HTTP-01 challenge responder handling only one connection at a time. A remote unauthenticated attacker can open idle connections during a certificate authority validation so the single worker waits up to five seconds per connection and the CA request times out, causing validation failure; sustained interference across renewals can let the certificate expire and make clients reject the server's TLS, although mail service continues on the current certificate until then. The issue is low-severity and availability-only, with no public exploit identified at time of analysis, and is fixed in 6.3.7, which serves up to 64 concurrent connections.
Samba's internal DNS server inserts unauthenticated TKEY registration requests into the TKEY name cache before rejecting them, allowing a remote unauthenticated attacker to exhaust the cache by flooding it with arbitrary TKEY names. Eviction of legitimate cache entries blocks TSIG-authenticated DNS query processing, producing a targeted denial of service against Active Directory environments relying on Samba's built-in DNS backend. No public exploit code or CISA KEV listing has been identified at time of analysis; a vendor patch is available from both Samba upstream and Red Hat.
Denial of service in F5 BIG-IP affects the Traffic Management Microkernel (TMM) when Bidirectional Forwarding Detection (BFD) is configured with static or dynamic routing protocols. Undisclosed traffic patterns cause TMM to stop processing BFD packets, triggering unintended failover of the configured routing protocol. Remote unauthenticated attackers can trigger this condition over the network with low complexity, resulting in availability loss for BFD-dependent routing operations.
Jazz Reporting Service versions up to 7.0.3 contains a vulnerability that allows attackers to an authenticated user on the network to affect the system's performance using co (CVSS 3.5).
When a WF200/WGM160P device is configured to operate as an Access Point, it may be vulnerable to a denial of service triggered by a malformed packet. The device may recover automatically or require a hard reset.
An unauthenticated remote attacker can exploit a denial-of-service vulnerability in the device's web server functionality by sending a specially crafted HTTP request with a malicious header,. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Insufficient resource pool in the core management mechanism for some Intel(R) Processors may allow an authenticated user to potentially enable denial of service via local access. Rated medium severity (CVSS 5.7), this vulnerability is low attack complexity. No vendor patch available.
Insufficient resource pool in Windows Kerberos allows an unauthorized attacker to deny service over a network. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Epss exploitation probability 39.5% and no vendor patch available.
Dell Wyse Management Suite, versions prior to WMS 5.1, contains an Insufficient Resource Pool vulnerability. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
In mlflow/mlflow version 2.17.2, the `/graphql` endpoint is vulnerable to a denial of service attack. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
