FreeBSD : clamav -- multiple vulnerabilities (dbd1f627-c43b-11e9-a923-9c5c8e75236a)

critical Nessus Plugin ID 128137

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Micah Snyder reports :

- An out of bounds write was possible within ClamAV&s NSIS bzip2 library when attempting decompression in cases where the number of selectors exceeded the max limit set by the library (CVE-2019-12900).
The issue has been resolved by respecting that limit.

- The zip bomb vulnerability mitigated in 0.101.3 has been assigned the CVE identifier CVE-2019-12625. Unfortunately, a workaround for the zip-bomb mitigation was immediately identified. To remediate the zip-bomb scan time issue, a scan time limit has been introduced in 0.101.4. This limit now resolves ClamAV's vulnerability to CVE-2019-12625.

Solution

Update the affected packages.
