libssh: libssh: stack buffer overflow in SFTP server longname construction

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 ...

CVE-2026-54758

Notepad++ prior to 8.9.7 contains a stack buffer overflow in the expandNppEnvironmentStrs function (RunDlg.cpp). The function copies a variable name between $( ) into a fixed-size wchar_t str[MAX_PATH] buffer without bounding the loop index, so a name of 260 or more characters can corrupt adjacen...

CVE-2026-45698 Netatalk has Integer Underflow → Stack Buffer Overflow in deletedir()

Netatalk is a Free and Open Source file server suite for Unix-like operating systems. In versions 3.1.19 through 4.4.2, a stack-based buffer overflow exists in the deletedir function of Netatalk's afpd daemon due to an integer underflow in the calculation of the remaining buffer size used for pat...

CVE-2026-45698

Affected: Netatalk afpd daemon (versions 3.1.19 through 4.4.2). Root cause: an unsigned integer underflow in deletedir() sets the remain size_t to SIZE_MAX, bypassing the boundary check and enabling an unbounded strcpy() of attacker-controlled filenames into a nearly full stack buffer. Impact: hi...
