Astra Linux – vulnerability in libtar

The thread function does not free the variable t-thbuf.gnulongname after allocating memory, which may lead to a memory leak...

Astra Linux – Vulnerability in libtar

An attacker who submits a crafted tar file with a size of 0 in the header struct field may be able to trigger a call to malloc0 for the variable gnulongname, resulting in an out-of-bounds read...

AlmaLinux 9.2 [TuxCare] Security Update: libssh / libssh-config / libssh-devel (ALMALINUX9.2:CLSA-2026:1776181240)

The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1776181240 advisory. - A flaw was found in libssh in which a malicious SFTP SSH File Transfer Protocol server can exploit this by sending a malformed 'longname'...

UBUNTU-CVE-2026-53600

async-tar is a tar archive reading/writing library for async Rust. Prior to version 0.6.1, async-tar mis-applies a buffered PAX size extension to an intermediary extension header a GNU longname L, a GNU longlink K, or a PAX x/g header instead of to the next file entry. POSIX requires a PAX...

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 ...

JLSEC-2026-783

A flaw was found in libssh in which a malicious SFTP SSH File Transfer Protocol server can exploit this by sending a malformed 'longname' field within an SSHFXPNAME message during a file listing operation. This missing null check can lead to reading beyond allocated memory on the heap. This can...

CVE-2026-15370

CVE-2026-15370 is a vulnerability in libssh where, during SFTP server directory listing, the longname field is built by unsafe string concatenation into a fixed-size stack buffer. This can allow sufficiently long attacker-controlled filenames to overflow the stack, potentially crashing the server...

Stack-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Stack-based Buffer Overflow in the construction of the longname field during SFTP server directory listing. An attacker can cause a crash or execute arbitrary code on the server by supplying specially crafted, excessively long filenames...
