CVE-2026-59845

A flaw was found in libssh. When ProxyCommand is used, an unchecked fork failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service...

CVE-2026-59845

A flaw was found in libssh. When ProxyCommand is used, an unchecked fork failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service. Mitigation To mitigate this issue, avoid using the ProxyComman...

CVE-2026-59844

A flaw was found in libssh. A remote authenticated client can issue SSHFXPREAD requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests. Mitigation No workaround available...

CVE-2026-59843

A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSHMSGCHANNELOPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service...

CVE-2026-59842 Libssh: libssh: information disclosure via short gssapi curve25519 public key

A flaw was found in libssh. During server-side GSSAPI key exchange, a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation, leading to an out-of-bounds heap read. This could allow a remote unauthenticated attacker to disclose small...

CVE-2026-15370

A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can overflow that stack buffer and may lead ...
