This update for clamav fixes the following issues:
clamav was updated to 0.103.0 to implement jsc#ECO-3010 and bsc#1118459.
- clamd can now reload the signature database without blocking
scanning. This multi-threaded database reload improvement was made
possible thanks to a community effort.
- Non-blocking database reloads are now the default behavior. Some
systems that are more constrained on RAM may need to disable
non-blocking reloads as it will temporarily consume two times as
much memory. We added a new clamd config option
ConcurrentDatabaseReload, which may be set to no.
- Fix clamav-milter.service (requires clamd.service to run)
- bsc#1119353, clamav-fips.patch: Fix freshclam crash in FIPS mode.
- Partial sync with SLE15.
Update to version 0.102.4
Accumulated security fixes:
- 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. (bsc#1174255)
- 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. (bsc#1174250)
