CVE-2026-15370Libssh: libssh: stack buffer overflow in sftp server longname construction

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Hardened Images; Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 9 Veröffentlicht: (vor 3 Monaten)

Beschreibung

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 to crashes or possible code execution on the server.

Schwachstellentyp (CWE): CWE-121
