XML::Bare versions through 0.53 for Perl have an unbounded character lookahead. The parserc_parse function attempts to check for multicharacter strings such as "<![CDATA" or element terminators such as ">" without checking that the offsets are within the buffer. Truncated strings such as "<a/" can trigger an out-of-bounds read.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3403-1 advisory.

    This update for perl-XML-Bare fixes the following issues

    - CVE-2026-13401: infinite loop when parsing malformed attributes in `parserc_parse` function     (bsc#1271640).
    - CVE-2026-57074: out-of-bounds read due to unbounded character lookahead in the `parserc_parse` function       (bsc#1271637).

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

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

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21435-1 advisory.

    Changes in perl-XML-Bare:

    - CVE-2026-13401: XML:Bare would hang when parsing malformed attributes (bsc#1271640)
    - CVE-2026-57074: Fixed unbounded character lookahead (bsc#1271637)

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

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

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

  - XML::Bare versions through 0.53 for Perl have an unbounded character lookahead. The parserc_parse function     attempts to check for multicharacter strings such as <![CDATA or element terminators such as > without     checking that the offsets are within the buffer. Truncated strings such as <a/ can trigger an out-of-     bounds read. (CVE-2026-57074)

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