______________________________________________________________________________
An update that solves 7 vulnerabilities, contains one feature and has one
errata is now available.
Description:
This update for clamav fixes the following issues:
clamav was updated to 0.103.0 to implement jsc#ECO-3010 and bsc#1118459.
o 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.
o Fix clamav-milter.service (requires clamd.service to run)
o bsc#1119353, clamav-fips.patch: Fix freshclam crash in FIPS mode.
o Partial sync with SLE15.
Update to version 0.102.4
Accumulated security fixes:
o 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)
o 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.
o 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)
o 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)
o 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.
o 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).
o CVE-2019-12900: An out of bounds write in the NSIS bzip2 (bsc#1149458)
o 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:
o ZIP bomb causes extreme CPU spikes (bsc#1144504)
Update to version 0.101.2 (bsc#1118459):
o Support for RAR v5 archive extraction.
o Incompatible changes to the arguments of cl_scandesc, cl_scandesc_callback,
and cl_scanmap_callback.
o Scanning options have been converted from a single flag bit-field into a
structure of multiple categorized flag bit-fields.
o 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
o Incompatible clamd.conf and command line interface changes.
o 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.
o For details, see https://blog.clamav.net/2018/12/
clamav-01010-has-been-released.html
