EulerOS 2.0 SP12 : popt (EulerOS-SA-2026-4518)

low Nessus Plugin ID 376681

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the popt packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacker to execute arbitrary code if the host application then unsafely processes the altered data.(CVE-2026-18739)

 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)

Tenable has extracted the preceding description block directly from the EulerOS popt security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected popt packages.
