EulerOS 2.0 SP12 : nmap (EulerOS-SA-2026-3287)

medium Nessus Plugin ID 343706

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6_get_data_primitive (libnetutil/netutil.cc), so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a crafted IPv6 response with a truncated extension header can trigger out-of-bounds reads and a crash during raw IPv6 scans.(CVE-2026-58058)

Tenable has extracted the preceding description block directly from the EulerOS nmap 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 nmap packages.
