The Log4j1XmlLayout from the Apache Log4j 1-to-Log4j 2 bridge fails to escape characters forbidden by the XML 1.0 standard, producing malformed XML output. Conforming XML parsers are required to reject documents containing such characters with a fatal error, which may cause downstream log...

golang.org/x/crypto/ssh/agent: SSH Agent servers: Denial of Service due to malformed messages

A flaw was found in the SSH Agent servers component golang.org/x/crypto/ssh/agent. This vulnerability allows a remote attacker to cause a denial of service DoS by sending a specially crafted, malformed message during new identity requests. The server fails to validate the size of these messages,...

golang.org/x/net/http2: golang.org/x/net/http2: Denial of Service due to malformed HTTP/2 frames

A flaw was found in golang.org/x/net/http2. A remote attacker can exploit this vulnerability by sending specially crafted HTTP/2 frames, which are data packets used in the HTTP/2 protocol. Due to a missing check for null values, processing these specific frames types 0x0a through 0x0f can cause t...

CVE-2026-5188 Integer underflow in X.509 SAN parsing in wolfSSL

An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name SAN extension of X.509 certificates.
