UBUNTU-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 ...

PT-2026-61926

Name of the Vulnerable Software and Affected Versions libssh affected versions not specified Description A flaw exists where a remote authenticated client can send SSH FXP READ requests with an arbitrarily large length. This causes a libssh SFTP server to allocate excessive memory, which can lead...

CVE-2026-59847: Incorrect Check of Function Return Value

A flaw was found in libssh. Incorrect AES-GCM finalization checks in builds using the OpenSSL backend can effectively remove integrity protection, allowing an in-path attacker to modify plaintext on the wire without detection...

CVE-2026-59844: Memory Allocation with Excessive Size Value

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...

PT-2026-61950

Name of the Vulnerable Software and Affected Versions libssh affected versions not specified Description A flaw exists in the gssapi-keyex path on servers where GSSAPIKeyExchange is enabled. The system fails to verify if the authenticated Kerberos principal is authorized for the requested local...

PT-2026-61857

Name of the Vulnerable Software and Affected Versions libssh affected versions not specified Description A flaw exists during server-side GSSAPI key exchange where a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation. This results in ...

PT-2026-61936

Name of the Vulnerable Software and Affected Versions libssh affected versions not specified Description A flaw exists in the handling of ProxyCommand where a malicious username expanded through the %r variable can inject shell metacharacters. This can lead to the exposure of environment variable...
