An update that fixes 5 vulnerabilities, contains one feature is now available.
Description:
This update for clamav fixes the following issues:
o Update to 0.103.0 to implement jsc#ECO-3010 and bsc#1118459
o This update incorporates incompatible changes that were introduced in
version 0.101.0.
o 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.
