- --------------------------BEGIN INCLUDED TEXT--------------------
Package : clamav
Version : 0.100.3+dfsg-0+deb8u1
CVE ID : CVE-2019-1787 CVE-2019-1788 CVE-2019-1789
Debian Bug :
Out-of-bounds read and write conditions have been fixed in clamav.
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.
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.
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
We recommend that you upgrade your clamav packages.
