---------------------------------------------------------------
Hi [~ggregory], more information about the issue.
Here is a [SNYK security
ticket|https://security.snyk.io/vuln/SNYK-JAVA-XERCES-31497]. The ticket
mentions that the issue has been resolved by patch 2.11.0.
Based on a
[comment|https://github.com/jeremylong/DependencyCheck/issues/4614#issuecomment-1203233304]
on Github, the issue was not resolved within Xerces itself (still fully
relying on Java defaults to provide sensible timeouts), but it's only resolved
because the JDK has built in a default timeout for FTP connections in response
to the CVE, so that over time the connections will time out and release the
hanging thread with a timeout exception.
In [Hans Aikema|https://github.com/aikebah]'s view, this default timeout is
still large enough to warrant the OSSINDEX security team to keep the issue for
Xerces open (with a 300k millisec timeout an attacker may well be capable of
triggering at least a significant service degradation).
Thank you.
Regards,
Albert
