ClamAV is an open source antivirus software
The launch of the new version of ClamAV 1.3.0 has just been presented along with the corrective versions ClamAV 1.2.2 and ClamAV 1.0.5, which after six months of development arrive with various bug fixes, support improvements and more.
For those unaware of ClamAV you should know that this is an open source antivirus and multiplatform (It has versions for Windows, GNU / Linux, BSD, Solaris, Mac OS X and other Unix-like operating systems).
ClamAV 1.3 Main New Features
The branch of ClamAV 1.3.0 is classified as non-LTS, which means that updates are released at least 4 months after first release of the next branch. Additionally, the ability to download the signature database for non-LTS branches is also offered for at least another 4 months after the release of the next version.
One of the standout features ClamAV 1.3.0 brings is the Support for extracting and scanning attachments found in files from the Microsoft OneNote section. OneNote analysis is enabled by default in ClamAV, but can be disabled if desired. To do this, there are several options:
- .conf file: You can disable OneNote scanning by setting “ScanOneNote no” in the clamd.conf file.
- from clamscan: When running the clamscan utility, you can specify the “–scan-onenote=no” option to disable OneNote scanning.
- From libclamav: If you are using libclamav, you can add the CL_SCAN_PARSE_ONENOTE flag to the parse options parameter to disable OneNote scanning.
Another improvement that this ClamAV 1.3.0 presents is the Improved support for decrypting PDF documents with a blank password, as well as checking clamd for the existence of the directory for temporary files, since it now checks the existence of the directory specified by TemporaryDirectory en clamd.conf.
Have solved several problems, including one related to when setting up static library compilation in CMake, installation of static libraries is guaranteed libclamav_rust, libclammspack, libclamunrar_iface and libclamunrar, used in libclamav and fixed an infinite loop when a file was deleted before a scan
On the part of the fixes that are integrated into ClamAV 1.2.2 and 1.0.5, Critical patches are mentioned that address important vulnerabilities, specifically, we fixed possible heap overflow read errors in the OLE2 file parser and a possible command injection vulnerability in the "VirusEvent" function of ClamAV's ClamD service.
