Summary

popt security update

Details

The popt library exists essentially for parsing command line options. Some specific advantages of popt are no global variables (allowing multiple passes in parsing argv), parsing an arbitrary array of argv-style elements (allowing parsing of command-line-strings from any source), a standard method of option aliasing, ability to exec external option filters, and automatic generation of help and usage messages.

Security Fix(es):

A flaw was found in popt. This vulnerability allows an attacker to provide specially crafted configuration content to a host, which, when loaded, can lead to a small memory corruption issue. This occurs because of an error in how the poptConfigFileToString function reallocates memory for buffers. Successful exploitation could result in heap metadata corruption, potentially causing the affected process to become unavailable (denial of service).(CVE-2026-18743)
