A flaw was found in GNU patch. An attacker can achieve arbitrary file creation outside the intended working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to missing validation during automatic patch reversal, absolute file paths in patch headers are accepted rather than rejected. Consequently, the utility can create files in arbitrary locations with the permissions of the executing user.

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2026:99161 advisory.

    The patch program applies diff files to originals. The diff command is used to compare an original to a     changed file. Diff lists the changes made to the file. A person who has the original file can then use the     patch command with the diff file to add the changes to their original file (patching the file).

    Security Fix(es):

    * patch: Filename validation bypass in reversal fallback allows file creation outside the working     directory (CVE-2026-115207)

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A flaw was found in GNU patch. An attacker can achieve arbitrary file creation outside the intended
    working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to
    missing validation during automatic patch reversal, absolute file paths in patch headers are accepted
    rather than rejected. Consequently, the utility can create files in arbitrary locations with the
    permissions of the executing user. (CVE-2026-115207)

The version of patch installed on the remote host is prior to 2.8.1. It is, therefore, affected by a vulnerability as referenced in the SSA:2026-296-02 advisory.

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

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 GNU patch. An attacker can achieve arbitrary file creation outside the intended     working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to     missing validation during automatic patch reversal, absolute file paths in patch headers are accepted     rather than rejected. Consequently, the utility can create files in arbitrary locations with the     permissions of the executing user. (CVE-2026-115207)

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