Package        : clamav
Version        : 0.101.4+dfsg-0+deb8u1
CVE ID         : CVE-2019-12625 CVE-2019-12900
Debian Bug     : 34359

It was discovered that clamav, the open source antivirus engine, is affected by
the following security vulnerabilities:

CVE-2019-12625

    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.
