Fedora 31: clamav 2020-dd0c20d985
Summary
Clam AntiVirus is an anti-virus toolkit for UNIX. The main purpose of this
software is the integration with mail servers (attachment scanning). The
package provides a flexible and scalable multi-threaded daemon, a command
line scanner, and a tool for automatic updating via Internet. The programs
are based on a shared library distributed with the Clam AntiVirus package,
which you can use with your own software. The virus database is based on
the virus database from OpenAntiVirus, but contains additional signatures
(including signatures for popular polymorphic viruses, too) and is KEPT UP
TO DATE.
ClamAV 0.102.4 is a bug patch release to address the following issues:
CVE-2020-3350
Fixed a vulnerability a malicious user could exploit to 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 (such as a critical system
file). The issue would affect users that use the --move or --remove options for
clamscan, clamdscan and clamonacc. For more information about AV quarantine
attacks using links, see RACK911 Lab's report
condition. Improper bounds checking resulted in an out-of-bounds read that could
cause a crash. The previous fix for this CVE in version 0.102.3 was incomplete.
This fix correctly resolves the issue. CVE-2020-3481
vulnerability in the EGG archive module in ClamAV 0.102.0 - 0.102.3 that could
cause a denial-of-service (DoS) condition. Improper error handling could cause 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 affected
versions.
