It is recommended that administrators running expat check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Package : expat Version : 2.1.0-6+deb8u6 CVE IDs : CVE-2019-15903 Debian Bug : #939394 It was discovered that there was a heap-based buffer overread vulnerability in expat, an XML parsing library. A specially-crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer overread. For Debian 8 "Jessie", this issue has been fixed in expat version 2.1.0-6+deb8u6. We recommend that you upgrade your expat packages.
