NVD Description

Note: Versions mentioned in the description apply only to the upstream libclammspack0 package and not the libclammspack0 package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

A vulnerability in the Mach-O file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition or possibly other expanded impacts as a result of&nbsp;memory corruption on an affected device.

This vulnerability is due to improper boundary checks for content in Mach-O files during scanning, which may result in an out-of-bounds buffer read. An attacker could exploit this vulnerability by submitting a crafted Mach-O file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
