Synopsis

The remote Fedora host is missing a security update.

Description

ClamAV 0.100.2 has been released! This is a patch release to address several vulnerabilities.

Fixes for the following ClamAV vulnerabilities: CVE-2018-15378:
Vulnerability in ClamAV's MEW unpacking feature that could allow an unauthenticated, remote attacker to cause a denial-of-service (DoS) condition on an affected device. Reported by Secunia Research at Flexera. Fix for a two-byte buffer over-read bug in ClamAV's PDF parsing code. Reported by Alex Gaynor. Fixes for the following vulnerabilities in bundled third-party libraries: CVE-2018-14680: An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. It does not reject blank CHM filenames. CVE-2018-14681: An issue was discovered in kwajd_read_headers in mspack/kwajd.c in libmspack before 0.7alpha. Bad KWAJ file header extensions could cause a one- or two-byte overwrite. CVE-2018-14682: An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. There is an off-by-one error in the TOLOWER() macro for CHM decompression. Additionally, 0.100.2 reverted 0.100.1's patch for CVE-2018-14679, and applied libmspack's version of the fix in its place

Other changes: Some users have reported freshclam signature update failures as a result of a delay between the time the new signature database content is announced and the time that the content-delivery-network has the content available for download. To mitigate these errors, this patch release includes some modifications to freshclam to make it more lenient, and to reduce the time that freshclam will ignore a mirror when it detects an issue. On-Access 'Extra Scanning,' an opt-in minor feature of OnAccess scanning on Linux systems, has been disabled due to a known issue with resource cleanup OnAccessExtraScanning will be re-enabled in a future release when the issue is resolved. In the mean-time, users who enabled the feature in clamd.conf will see a warning informing them that the feature is not active.
