Debian Security Advisory
DLA-1912-1 expat -- LTS security update
- Date Reported:
- 06 Sep 2019
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2019-15903.
- More information:
It was discovered that there was a heap-based buffer overread vulnerability in expat, an XML parsing library.
In libexpat before 2.2.8, 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 over-read.
For Debian 8
Jessie, these problems have been fixed in version 2.1.0-6+deb8u6.
We recommend that you upgrade your expat packages.
