CVE-2026-77584

A flaw was found in Tor where a malicious client could trigger a use-after-free UAF vulnerability. This occurs when the software fails to properly manage memory after a circuit is freed, specifically due to the improper handling of CONFLUXLINK cells on circuits with attached streams. By sending a...

SUSE 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...

CVE-2026-77584

Tor before 0.4.9.10 fails to reject a CONFLUX_LINK cell on a circuit with attached streams; a malicious client sends RELAY_COMMAND_BEGIN first, orphaning an exit stream that leaves a dangling circuit back-pointer and triggers use-after-free when the circuit is freed. CVSS 3.1 scores 7.0 (HIGH). F...

BIT-ELASTICSEARCH-2026-72639 Memory Allocation with Excessive Size Value in Elasticsearch Highlighting Leading to Denial of Service

Elasticsearch does not enforce an upper bound on a user-supplied count accepted by a search highlighting option, and the allocation derived from that count is not accounted against any circuit breaker. An authenticated user holding only read privileges on a single searchable index can submit one...
