EulerOS 2.0 SP11 : perl-Storable (EulerOS-SA-2026-4272)

critical Nessus Plugin ID 364995

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.

 retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value.

 A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.(CVE-2026-57433)

Tenable has extracted the preceding description block directly from the EulerOS perl-Storable 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-Storable packages.
