References:        #1118459 #1171981 #1174250 #1174255
Cross-References:  CVE-2020-3123 CVE-2020-3327 CVE-2020-3341 CVE-2020-3350
Affected Products:
                   SUSE Linux Enterprise Server 11-SP4-LTSS
                   SUSE Linux Enterprise Point of Sale 11-SP3

                   SUSE Linux Enterprise Debuginfo 11-SP3

An update that fixes 5 vulnerabilities, contains one feature is now available.


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.
