Title: | Security update for clamav (Important) |
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) * Fix freshclam crash in FIPS mode. (bsc#1119353)
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)
- Increase the startup timeout of clamd to 5 minutes to cater for the grown virus database as a workaround until clamd has learned to talk to systemd to extend the timeout as long as needed. (bsc#1151839)
