SUSE CVE-2026-77638

Tor before 0.4.9.11 is prone to a race condition where in just the right circumstances a rendezvous point could man-in-the-middle impersonate the onion service that the client was trying to reach...

EUVD-2026-63665

tor before 0.4.9.9 was prone to an out-of-bounds write when parsing a consensus or detached signature with unexpected signature digest type. Impact is minor for most Tor roles, but potentially major for directory authorities. This is TROVE-2026-019...

Linux Distros Unpatched Vulnerability : CVE-2026-77640

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tor before 0.4.9.9 was prone to an infinite loop when decompressing a truncated zlib/gzip stream with done=1. A truncated stream never reaches ZSTREAMEND, causi...

Linux Distros Unpatched Vulnerability : CVE-2026-77584

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Tor before 0.4.9.10 did not reject a CONFLUXLINK cell that arrives on a circuit which already has attached streams. A malicious client could send a...

Linux Distros Unpatched Vulnerability : CVE-2026-77587

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Tor before 0.4.9.11 is prone to a use-after-free and potential double free of a conflux object when a recovery leg revives a conflux set whose last linked leg h...

Linux Distros Unpatched Vulnerability : CVE-2026-77639

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Tor before 0.4.9.9 was prone to a compression bomb bypass where an attacker could concatenate many gzip or zlib sub-streams, each just under the per-stream...

Linux Distros Unpatched Vulnerability : CVE-2026-77641

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tor before 0.4.9.9 was prone to a NULL write after free when sending a CONFLUXSWITCH cell fails. The return value of relaysendcommandfromedge was ignored, so a...

DEBIAN-CVE-2026-77640

tor before 0.4.9.9 was prone to an infinite loop when decompressing a truncated zlib/gzip stream with done=1. A truncated stream never reaches ZSTREAMEND, causing zlib to return ZBUFERROR with no input remaining, which bufaddcompress mistook for a full output buffer and retried forever. Fixed by...

CVE-2026-77641

tor before 0.4.9.9 was prone to a NULL write after free when sending a CONFLUXSWITCH cell fails. The return value of relaysendcommandfromedge was ignored, so a send failure which calls circuitmarkforclose and removes the leg via cfxdelleg would go undetected, causing the caller to write to the...

CVE-2026-77639

Tor before 0.4.9.9 was prone to a compression bomb bypass where an attacker could concatenate many gzip or zlib sub-streams, each just under the per-stream detection threshold, to avoid the compression bomb check entirely. This is TROVE-2026-022...

DEBIAN-CVE-2026-77584

Tor before 0.4.9.10 did not reject a CONFLUXLINK cell that arrives on a circuit which already has attached streams. A malicious client could send a RELAYCOMMANDBEGIN before the CONFLUXLINK on the same circuit, attaching an exit stream that would later end up orphan leaving a dangling circuit...
