------------------------------------------------------------------------- Debian LTS Advisory DLA-3267-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Markus Koschany January 11, 2023 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : libxstream-java Version : 1.4.11.1-1+deb10u4 CVE ID : CVE-2022-41966 Debian Bug : 1027754 XStream serializes Java objects to XML and back again. Versions prior to 1.4.11.1-1+deb10u4 may allow a remote attacker to terminate the application with a stack overflow error, resulting in a denial of service only via manipulation of the processed input stream. The attack uses the hash code implementation for collections and maps to force recursive hash calculation causing a stack overflow. This update handles the stack overflow and raises an InputManipulationException instead. For Debian 10 buster, this problem has been fixed in version 1.4.11.1-1+deb10u4. 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 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS
