Libevent is an event notification library. Prior to 2.2.2-alpha, libevent can dereference invalid list pointers in ws.c when evwsnewsession enters its error path after evhttpstartws succeeds but buffereventenablelocking fails. evwsconnectionfree sees a non-null httpserver and unconditionally call...

CVE-2026-63381

Libevent (event notification library) contains a use-after-free in buffer.c when evbuffer_add_buffer_reference processes an output buffer whose out_total_len is zero. The function evbuffer_free_all_chains frees the initial empty chain without resetting outbuf->first, outbuf->last, or outbuf...

kbd: Local privilege escalation in openvt via incorrect process owner verification allowing passwordless root login

openvt -u is intended to identify the owner of the current VT and then execute login as that user from a privileged context. In the documented kbrequest/init usage, the ownership test in authenticateuser relies on stat"/proc//fd/0". stat on /proc//fd/0 follows the symlink to the underlying TTY...

GHSA-89V8-RHWQ-HF77 asteval has a Sandbox Escape via BaseException Subclasses

Summary An attacker who can supply expressions to asteval.Interpreter.eval can raise SystemExit, KeyboardInterrupt, GeneratorExit, or BaseException from inside the sandbox. These exceptions are subclasses of BaseException but not Exception, so they bypass the except Exception: safety net in both...

GHSA-42CJ-99W8-CP2P OpenTelemetry-Go: Unsynchronized baggage map can panic under concurrent access

Summary go.opentelemetry.io/otel/bridge/opentracing introduced an unsynchronized extraBaggageItems map on bridgeSpan. One goroutine can write this map through Span.SetBaggageItem while another goroutine reads and iterates it during correlation baggage propagation, which can trigger Go's fatal...

Improper Locking

Overview Affected versions of this package are vulnerable to Improper Locking through the bridgeSpan baggage handling in bridge/opentracing/bridge.go. An attacker can crash the process by causing one goroutine to call Span.SetBaggageItem while another goroutine propagates correlation baggage from...

linkify-it: linkify-it: Denial of Service via algorithmic complexity vulnerability
