Description

Details for this vulnerability have not been published by NIST at this point. Descriptions from software vendor advisories for this issue are provided below.

From VID-DBD1F627-C43B-11E9-A923-9C5C8E75236A:

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.
