EulerOS 2.0 SP11 : open-iscsi (EulerOS-SA-2026-4260)

medium Nessus Plugin ID 365068

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

A stack buffer overflow vulnerability exists in the idbm_recinfo_config() function in open-iscsi (iscsi- initiator-utils). An attacker can craft a malicious SendTargets TargetName containing newline characters and oversized injected keys or values to inject extra configuration lines into persisted node records.
When the record is reparsed, due to missing bounds checking, a stack buffer overflow occurs, leading to denial of service or potential memory corruption. The affected component is usr/idbm.c:idbm_recinfo_config in iscsi-initiator-utils, with attacker-controlled input reaching it through SendTargets handling in usr/discovery.c.(CVE-2026-18724)

An Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in open- iscsi allows remote MITM attackers to create root-owned files outside the database and inject lines into the record.

This issue affects open-iscsi: from through 668ca1df9c9a1e9bdd5c999ae1d67c9c8909237e.(CVE-2026-44943)

Tenable has extracted the preceding description block directly from the EulerOS open-iscsi 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 open-iscsi packages.
