high Nessus Plugin ID 363505
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
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 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 filename to popen(), so shell metacharacters execute as the receiving user. (CVE-2026-105841)
Note that Nessus relies on the presence of the package as reported by the vendor.
