"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.

Thanks to Martin Simmons for reporting the issue here.

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."
