EulerOS 2.0 SP12 : perl-HTML-Parser (EulerOS-SA-2026-3368)

high Nessus Plugin ID 343736

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the perl-HTML-Parser package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

HTML::Entities versions before 3.84 for Perl read freed heap memory in _decode_entities.

The XS routine backing HTML::Entities::_decode_entities cached a pointer (repl) into the entity-value SV returned by hv_fetch on the entity2char hash. When the input SV was identical to a value SV in that hash, and that value contained its own key as an entity reference, a later call to grow_gap() reallocated the SV's PV buffer and freed the backing allocation that repl still pointed into. The subsequent copy loop read repl_len bytes from the freed allocation.

The read may disclose adjacent heap contents into the destination SV.(CVE-2026-8829)

Tenable has extracted the preceding description block directly from the EulerOS perl-HTML-Parser security advisory.

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

Solution

Update the affected perl-HTML-Parser packages.
