Linux Distros Unpatched Vulnerability : CVE-2026-105840

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - lrzsz before 0.13.0 contains a path traversal vulnerability in the lrz receive utility's restricted mode that allows malicious ZMODEM senders to write files...

CVE-2026-105840

A flaw was found in lrzsz. The lrz receive utility fails to properly sanitize absolute file paths in restricted mode, only checking for relative path traversal sequences. A remote attacker transmitting files can exploit this vulnerability to write or overwrite arbitrary files outside the intended...

CVE-2026-105842

A flaw was found in lrzsz. A remote attacker acting as a malicious sender can trigger a heap-based buffer overflow by providing an excessively long filename during a ZMODEM file transfer. This flaw allows the attacker to corrupt memory and crash the application, resulting in a Denial of Service...

AZL-106670 CVE-2026-105842 affecting package lrzsz 0.12.20-50

lrzsz before 0.13.0 contains a heap-based buffer overflow vulnerability in procheader of the lrz receive utility when copying overlong sender-supplied filenames into Pathname. Malicious ZMODEM senders can supply filenames up to 8192 bytes, overflowing the buffer via sprintf in pipe mode or strcpy...

AZL-106673 CVE-2026-105841 affecting package lrzsz 0.12.20-50

lrzsz before 0.13.0 contains an OS command injection vulnerability in the lrz receive utility's pipe mode that allows remote senders to execute commands by supplying crafted filenames. When lrz runs under a suffixed name such as lrztar, procheader in src/lrz.c passes the unescaped ZMODEM/YMODEM...

AZL-106667 CVE-2026-105840 affecting package lrzsz 0.12.20-50

lrzsz before 0.13.0 contains a path traversal vulnerability in the lrz receive utility's restricted mode that allows malicious ZMODEM senders to write files outside the current directory using absolute pathnames. Because checkpath in src/lrz.c only rejects '../' sequences unless built with...
