Arch Linux Security Advisory ASA-202506-2
=========================================
Severity: Low
Date : 2025-06-05
CVE-ID : CVE-2025-5399
Package : curl
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-2895
Summary
=======
The package curl before version 8.14.1-1 is vulnerable to denial of
service.
Resolution
==========
Upgrade to 8.14.1-1.
# pacman -Syu "curl>=8.14.1-1"
The problem has been fixed upstream in version 8.14.1.
Workaround
==========
None.
Description
===========
Due to a mistake in libcurl's WebSocket code, a malicious server can
send a particularly crafted packet which makes libcurl get trapped in
an endless busy-loop.
There is no other way for the application to escape or exit this loop
other than killing the thread/process. This might be used to DoS
libcurl-using application.
Impact
======
A remote attacker can send a specially crafted WebSocket frame that
triggers an infinite busy-loop in libcurl, causing the application to
hang indefinitely potentially leading to a denial of service.
