Description
This security bulletin contains information about 1 security vulnerability.
1) Improper input validation (CVE-ID: CVE-2018-19857)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to improper handling of magic cookies in Core Audio Format (CAF) files, which could result in an uninitialized memory read in the CAF demuxer.
