Title
Обновление DLA-2924-1 -- устранение уязвимостей в libxstream-java
Description
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.

Comment
: 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.
