=========================================
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.
