{"id":"CVE-2026-116775","published":"2026-10-27T21:18:06.103","lastModified":"2026-10-27T21:18:06.330","description":"pageant provides a PageantStream type that implements AsyncRead and AsyncWrite traits and can be used to communicate with a running Pageant instance. From 0.2.0 until 0.2.5, PageantStream::new in pageant/src/wmmessage.rs trusts a peer-controlled four-byte length prefix and buffers until len + 4 bytes are available without checking the fixed _AGENT_MAX_MSGLEN transport capacity. An application that bridges an SSH forwarded-agent channel to the raw stream can allow a malicious server to force large allocations or retain a partially filled frame, causing client memory exhaustion. This issue is fixed in version 0.2.5.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Eugeny/russh/commit/69e4b55513eaa8ac9d2ad4236f13171fc164e10a","tags":[]},{"url":"https://github.com/Eugeny/russh/releases/tag/v0.65.0","tags":[]},{"url":"https://github.com/Eugeny/russh/security/advisories/GHSA-662x-8wvj-2276","tags":[]}],"exploitRefs":[{"url":"https://github.com/Eugeny/russh/commit/69e4b55513eaa8ac9d2ad4236f13171fc164e10a","tags":[]},{"url":"https://github.com/Eugeny/russh/releases/tag/v0.65.0","tags":[]},{"url":"https://github.com/Eugeny/russh/security/advisories/GHSA-662x-8wvj-2276","tags":[]}],"hasPoc":true,"ai":null}
