EulerOS 2.0 SP15 : patch (EulerOS-SA-2026-3932)

medium Nessus Plugin ID 364065

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 GNU patch is vulnerable to a NULL pointer dereference when processing a specially crafted unified-diff patch file. Improper handling of consecutive end-of-file newline markers can corrupt internal hunk (single block of changes in diff) data structures, causing the application to pass a NULL pointer to fwrite() during patch processing._x000D_ An attacker can trigger this condition with a malicious patch file, causing the utility to crash and resulting in a denial of service._x000D_
 _x000D_
 _x000D_
 _x000D_ This issue has been fixed in the commit e6d6a4e021660679d7fc9150f981d4920f722313(CVE-2026-56288)

 GNU patch is vulnerable to a denial of service (DoS) due to improper validation of hunk (single block of changes in diff) line offsets in unified-diff input. A specially crafted patch can specify an extremely large line number, causing the application to enter an effectively infinite processing loop while attempting to locate the requested position._x000D_ This results in excessive CPU consumption and prevents the process from completing._x000D_ An attacker can trigger this behavior by supplying a malicious patch file, causing the utility to become unresponsive and require manual termination._x000D_
 _x000D_
 _x000D_
 _x000D_ This issue has been fixed in the commit faba04ef4f2b410257f76c1b9dc85e350929c4b9(CVE-2026-56289)

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