Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS in the handling of SFTP responses with unknown request IDs. An attacker can cause unbounded memory growth and disrupt client operations by sending specially crafted responses from a malicious SFTP server. Workaroun...

SUSE CVE-2026-53994

ProFTPD modsftp contains a heap-based buffer overflow reachable by an authenticated SFTP user. The fxppacketread function accepts the attacker-supplied 32-bit big-endian SFTP packet length without a minimum sanity check. A value of 0 causes an unsigned subtraction elsewhere in the read path to...

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 ...
