<summary>Security update for clamav</summary>
<description>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)
* CVE-2020-3341: Fix a vulnerability in the PDF parsing module in
ClamAV 0.101 - 0.102.2 that could cause a Denial-of-Service (DoS)
condition. Improper size checking of a buffer used to initialize AES
decryption routines results in an out-of-bounds read which may cause
a crash. (bsc#1171981)
* CVE-2020-3123: A denial-of-service (DoS) condition may occur when
using the optional credit card data-loss-prevention (DLP) feature.
Improper bounds checking of an unsigned variable resulted in an
out-of-bounds read, which causes a crash.
* CVE-2019-15961: A Denial-of-Service (DoS) vulnerability may
occur when scanning a specially crafted email file as a result
of excessively long scan times. The issue is resolved by
implementing several maximums in parsing MIME messages and by
optimizing use of memory allocation. (bsc#1157763).
* CVE-2019-12900: An out of bounds write in the NSIS bzip2
(bsc#1149458)
* CVE-2019-12625: Introduce a configurable time limit to mitigate
zip bomb vulnerability completely. Default is 2 minutes,
configurable useing the clamscan --max-scantime and for clamd
using the MaxScanTime config option (bsc#1144504)
Update to version 0.101.3:
* ZIP bomb causes extreme CPU spikes (bsc#1144504)
Update to version 0.101.2 (bsc#1118459):
* Support for RAR v5 archive extraction.
* Incompatible changes to the arguments of cl_scandesc,
cl_scandesc_callback, and cl_scanmap_callback.
* Scanning options have been converted from a single flag
bit-field into a structure of multiple categorized flag
bit-fields.
* The CL_SCAN_HEURISTIC_ENCRYPTED scan option was replaced by
2 new scan options: CL_SCAN_HEURISTIC_ENCRYPTED_ARCHIVE, and
CL_SCAN_HEURISTIC_ENCRYPTED_DOC
* Incompatible clamd.conf and command line interface changes.
* Heuristic Alerts" (aka "Algorithmic Detection") options have
been changed to make the names more consistent. The original
options are deprecated in 0.101, and will be removed in a
future feature release.
