Debian LTS Advisory DLA-2924-1 [email protected]
https://www.debian.org/lts/security/ Chris Lamb
February 15, 2022 https://wiki.debian.org/LTS
Package : libxstream-java
Version : 1.4.11.1-1+deb9u5
CVE ID : CVE-2021-43859
It was discovered that there was a potential remote denial of service
(DoS) attack in XStream, a Java library used to serialize objects to
XML and back again.
An attacker could have consumed 100% of the CPU resources, but the
library now monitors and accumulates the time it takes to add
elements to collections, and throws an exception if a set threshold
is exceeded.
For Debian 9 "Stretch", this problem has been fixed in version
1.4.11.1-1+deb9u5.
We recommend that you upgrade your libxstream-java packages.
For the detailed security status of libxstream-java please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/libxstream-java
