Upgrade BabelDOC to version 0.7.0 or later, where this vulnerability is fixed. No other mitigation or workaround is indicated.
Description
BabelDOC versions from 0.3.61 up to but not including 0.7.0 contain a resource exhaustion vulnerability. This flaw allows remote attackers to cause excessive CPU and memory consumption by submitting a crafted PDF with an embedded ToUnicode CMap that declares extremely large bfrange and cidrange spans. This triggers billions of loop iterations in the translation worker, effectively stalling it. The vulnerability is fixed in version 0.7.0.
