A flaw was found in libXpm. A local user with low privileges could exploit an Out-of-Bounds Read vulnerability in the `xpmNextWord()` function by processing a specially crafted or very small XPM (X PixMap) image file. This improper validation of file boundaries can cause an internal pointer to read beyond the file's end, leading to application crashes and Denial of Service conditions.

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

    A vulnerability was found in X.org libXpm up to 3.5.4. It has been classified as problematic.CWE is     classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the     intended buffer.This is going to have an impact on confidentiality.Upgrading to version 3.5.19 eliminates     this vulnerability. Applying the patch 5448e1bd is able to eliminate this problem. The bugfix is ready for     download at gitlab.freedesktop.org. The best possible mitigation is suggested to be upgrading to the     latest version.(CVE-2026-4367)

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

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

The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:20953-1 advisory.

    This update for libXpm fixes the following issue:

    - CVE-2026-4367: out-of-bounds read in `xpmNextWord()` (bsc#1260928).

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

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

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1656 advisory.

    As per upstream advisory: libXpm Out-of-bounds read in xpmNextWord() (CVE-2026-4367)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The version of libXpm installed on the remote host is prior to 3.5.12-9. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3291 advisory.

    As per upstream advisory: libXpm Out-of-bounds read in xpmNextWord() (CVE-2026-4367)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the dea605e6-41c9-11f1-8455-901b0e13f1a0 advisory.

    The X.Org project reports:

                libXpm uses a number of internal helper functions to parse the XPM                 file format.
                One of these internal functions, xpmNextString(), checks for the                 NULL terminator when looking for the end of the current string but                 not when looking for the beginning of the next string.
                A small XPM file with a malformed color table definition may cause                 the function xpmNextWord(), called from xpmParseColors() following                 a call to xpmNextString(), to start past the actual end of the file,                 causing an out-of-bound read.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in libXpm. A local user with low privileges could exploit an Out-of-Bounds Read     vulnerability in the `xpmNextWord()` function by processing a specially crafted or very small XPM (X     PixMap) image file. This improper validation of file boundaries can cause an internal pointer to read     beyond the file's end, leading to application crashes and Denial of Service conditions. (CVE-2026-4367)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of libXpm installed on the remote host is prior to 3.5.19. It is, therefore, affected by a vulnerability as referenced in the SSA:2026-111-01 advisory.

    New libXpm packages are available for Slackware 15.0 and -current to fix a security issue.
