Summary

The remote host is missing an update for the 'clamav' package(s) announced via the DSA-1953-1 advisory.

Insight

Insight

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.
