Synopsis

The remote Fedora host is missing a security update.

Description

ClamAV 0.102.3 is a bug patch release to address the following issues.

- CVE-2020-3327: Fix a vulnerability in the ARJ archive parsing module in ClamAV 0.102.2 that could cause a Denial-of-Service (DoS) condition. Improper bounds checking of an unsigned variable results in an out-of-bounds read which causes a crash. Special thanks to Daehui Chang and Fady Othman for helping identify the ARJ parsing vulnerability.

- 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. Bug found by OSS-Fuzz.

- Fix 'Attempt to allocate 0 bytes' error when parsing some PDF documents.

- Fix a couple of minor memory leaks.

----

- Add upstream patch to fix 'Attempt to allocate 0 bytes' errors while scanning certain PDFs

- Do not log freshclam output to syslog by default - creates double entries in the journal (bz#1822012)

- (#1820069) add try-restart clamav-freshclam.service on logrotate

- Enable prelude support (bz#1829726)

- Move /etc/clamd.d/scan.conf to clamav-filesystem

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
