CVE ID : CVE-2022-43680
Debian Bug : 1022743
A heap use-after-free vulnerability after overeager destruction of a
shared DTD in the XML_ExternalEntityParserCreate function in Expat, an
XML parsing C library, may result in denial of service or potentially
the execution of arbitrary code.
For the stable distribution (bullseye), this problem has been fixed in
version 2.2.10-2+deb11u5.
