Arch Linux Security Advisory ASA-202102-43
=========================================
Severity: Medium
Date : 2021-02-27
CVE-ID : CVE-2020-13949
Package : thrift
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-1568
Summary
======
The package thrift before version 0.14.0-1 is vulnerable to denial of
service.
Resolution
=========
Upgrade to 0.14.0-1.
# pacman -Syu "thrift>=0.14.0-1"
The problem has been fixed upstream in version 0.14.0.
Workaround
=========
None.
Description
==========
Applications using Thrift before version 0.14.0 would not error upon
receiving messages declaring containers of sizes larger than the
payload. As a result, malicious RPC clients could send short messages
which would result in a large memory allocation, potentially leading to
denial of service.
Impact
=====
Malicious clients could send crafted messages crashing the server.
