CVE-2026-107575 Inefficient Algorithmic Complexity in hMailServer

Inefficient algorithmic complexity in the SPF macro expansion of Progressive Robot hMailServer 6.3.4 and 6.3.5 allows a remote unauthenticated attacker to consume worker-thread time by publishing a crafted SPF record. RFC 7208 section 7.1 requires a name too long to look up to lose whole labels...

CVE-2026-98364

A flaw was found in the Linux kernel's IPsec XFRM networking subsystem. A race condition occurs when creating policy bundles while a network device is concurrently removed, leading to a use-after-free condition where the kernel accesses already-freed device memory. A local attacker can exploit th...

CVE-2026-104658

The Linux live-update apply helper hmailserver-update of Progressive Robot hMailServer 6.3.4 and 6.3.5 runs as root on a request file written by the unprivileged hmailserver service account, and took from that request the program used to verify an AppImage update's signature and the systemd unit ...

CVE-2026-103649

Missing network timeouts in the Linux builds of Progressive Robot hMailServer 6.3.0 through 6.3.5 allow a remote attacker to hold server threads indefinitely and so stop outbound mail delivery denial of service. The server set its socket timeouts in the form Windows takes, which Linux refuses, an...

CVE-2026-103010

Heap-based buffer overflow in the legacy Blowfish decryption routine BlowFishEncryptor::DecryptFromString in Progressive Robot hMailServer 6.0.0 through 6.3.3 on Windows allows a local interactive user with no hMailServer credentials to write bytes of their choosing past the end of a 255-byte hea...

CVE-2026-103011

Heap-based buffer overflow in the legacy Blowfish encryption routine BlowFishEncryptor::Encode, called by EncryptToString in Progressive Robot hMailServer 6.0.0 through 6.3.5 allows an authenticated mailbox user to cause a denial of service service crash, and possibly other unspecified impact. In...
