EulerOS 2.0 SP12 : mtr (EulerOS-SA-2026-3359)

medium Nessus Plugin ID 343680

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 mtr is vulnerable to Out-of-bounds read vulnerability in ipinfo_lookup() function. An attacker who can influence the TXT response used for AS lookups can trigger this bug by returning a DNS response that is larger than 512 bytes and uses a crafted compression pointer in the answer NAME field. ipinfo_lookup() function uses the length of the response as the end-of-message boundary for dn_expand() function. The result is a reliable crash. This issue exists in the mtr through version 0.96 and it was fixed in commit 48e1794414d338ce47abc0f27c25ade8788af9c3.(CVE-2026-14461)

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

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

Solution

Update the affected mtr packages.
