Package : expat
Version : 2.1.0-6+deb8u5
CVE ID : CVE-2018-20843
Debian Bug : 931031
It was discovered that Expat, an XML parsing C library, did not properly
handle XML input including XML names that contain a large number of
colons, potentially resulting in denial of service.
For Debian 8 "Jessie", this problem has been fixed in version
2.1.0-6+deb8u5.
We recommend that you upgrade your expat packages.
