XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible.

    XStream is a simple java library to serialize objects to XML     and back again. Two vulnerabilities were fixed:

    CVE-2021-43859:

      XStream can cause a Denial of Service (DoS) by injecting highly       recursive collections or maps

    CVE-2024-47072

      XStream was vulnerable to a Denial of Service attack due       to stack overflow from a manipulated binary input stream

    For Debian 11 bullseye, this problem has been fixed in version     1.4.15-3+deb11u3.

    We recommend that you upgrade your libxstream-java packages.

The remote Debian 9 host has a package installed that is affected by a vulnerability as referenced in the dla-2924 advisory.

    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.
