EulerOS 2.0 SP12 : perl (EulerOS-SA-2026-3289)

critical Nessus Plugin ID 343725

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 Socket versions before 2.041 for Perl have an out-of-bounds heap read.

 In Socket.xs, pack_ip_mreq_source() checks the length of its source argument before the argument is read, so the check tests the byte length carried over from the preceding multiaddr argument instead. Both addresses occupy a 4-byte field, so a valid multiaddr lets a source of any length pass the check, and the source is then copied into the 4-byte imr_sourceaddr field with a fixed-size copy. A source shorter than 4 bytes is not rejected, and the copy reads up to 3 bytes past the end of its buffer.

 Calling pack_ip_mreq_source() with a source value shorter than 4 bytes copies adjacent heap memory into the returned packed structure.(CVE-2026-12087)

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