Debian 8 Jessie: DLA-1759-1 Critical Clamav Out-of-Bounds Fix

CVE-2019-1787

An out-of-bounds heap read condition may occur when scanning PDF
documents. The defect is a failure to correctly keep track of the number
of bytes remaining in a buffer when indexing file data.

CVE-2019-1788

An out-of-bounds heap write condition may occur when scanning OLE2 files
such as Microsoft Office 97-2003 documents. The invalid write happens when
an invalid pointer is mistakenly used to initialize a 32bit integer to
zero. This is likely to crash the application.

CVE-2019-1789

An out-of-bounds heap read condition may occur when scanning PE files
(i.e. Windows EXE and DLL files) that have been packed using Aspack as a
result of inadequate bound-checking.


For Debian 8 "Jessie", these problems have been fixed in version
