Arch Linux Security Advisory ASA-202102-15

Severity: Medium
Date : 2021-02-07
CVE-ID : CVE-2021-21702
Package : php
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-1531

Summary

The package php before version 8.0.2-1 is vulnerable to denial of
service.

Resolution

Upgrade to 8.0.2-1.

pacman -Syu “php>=8.0.2-1”

The problem has been fixed upstream in version 8.0.2.

Workaround

None.

Description

A security issue was found in PHP before versions 8.0.2, 7.4.15 and
7.3.27. PHP will crash with a SIGSEGV via null-pointer dereference
whenever an XML is provided to the SoapClient query() function without
an existing field. The issue is fixed in versions 8.0.2, 7.4.15 and
7.3.27.

Impact

A remote attacker might be able to crash PHP via a specially crafted
XML payload.
