security advisory denial of service software update debian clamav out-of-bounds write

Summary

Denial of Service (DoS) vulnerability, resulting from excessively long scan
times caused by non-recursive zip bombs. Among others, this issue was
mitigated by introducing a scan time limit.

CVE-2019-12900

Out-of-bounds write in ClamAV's NSIS bzip2 library when attempting
decompression in cases where the number of selectors exceeded the max limit
set by the library.

This update triggers a transition from libclamav7 to libclama9. As a result,
several other packages will be recompiled against the fixed package after the
release of this update: dansguardian, havp, python-pyclamav, c-icap-modules.

For Debian 8 "Jessie", these problems have been fixed in version
0.101.4+dfsg-0+deb8u1.

We recommend that you upgrade your clamav packages.
