CVE-2020-35965 [MEDIUM] FFmpeg vulnerabilities
Title: FFmpeg vulnerabilities
Summary: Several security issues were fixed in FFmpeg.
It was discovered that FFmpeg did not properly verify certain input when
processing video and audio files. An attacker could possibly use this to send
specially crafted input to the application, force a division by zero, and
cause a denial of service (application crash). (CVE-2020-20445, CVE-2020-20446,
CVE-2020-20453, CVE-2020-20892)
It was discovered that FFmpeg did not properly perform certain bit shift and
memory operations. An attacker could possibly use this issue to expose
sensitive information. (CVE-2020-20902)
It was discovered that FFmpeg did not properly perform memory management
operations in various of its functions. An attacker could possibly use this
issue to send specially crafted input
