- Update to 0.102.4
* CVE-2020-3350: Fix a vulnerability wherein a malicious user could
replace a scan target's directory with a symlink to another path
to trick clamscan, clamdscan, or clamonacc into removing or moving
a different file (eg. a critical system file). The issue would
affect users that use the --move or --remove options for clamscan,
clamdscan, and clamonacc.
* CVE-2020-3327: Fix a vulnerability in the ARJ archive parsing
module in ClamAV 0.102.3 that could cause a Denial-of-Service
(DoS) condition. Improper bounds checking results in an
out-of-bounds read which could cause a crash. The previous fix for
this CVE in 0.102.3 was incomplete. This fix correctly resolves
the issue.
* CVE-2020-3481: Fix a vulnerability in the EGG archive module in
ClamAV 0.102.0 - 0.102.3 could cause a Denial-of-Service (DoS)
condition. Improper error handling may result in a crash due to a
NULL pointer dereference. This vulnerability is mitigated for
those using the official ClamAV signature databases because the
file type signatures in daily.cvd will not enable the EGG archive
parser in versions affected by the vulnerability.
