{"id":"USN-6449-2","summary":"ffmpeg regression","details":"\nUSN-6449-1 fixed vulnerabilities in FFmpeg. Unfortunately that update\ncould introduce a regression in tools using an FFmpeg library, like VLC. \n\nThis updated fixes the problem. We apologize for the inconvenience.\n\nOriginal advisory details: \n\nIt was discovered that FFmpeg incorrectly managed memory resulting \nin a memory leak. An attacker could possibly use this issue to cause\na denial of service via application crash. This issue only \naffected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-22038)\n\nIt was discovered that FFmpeg incorrectly handled certain input files, \nleading to an integer overflow. An attacker could possibly use this issue\nto cause a denial of service via application crash. This issue only \naffected Ubuntu 20.04 LTS. (CVE-2020-20898, CVE-2021-38090, \nCVE-2021-38091, CVE-2021-38092, CVE-2021-38093, CVE-2021-38094)\n\nIt was discovered that FFmpeg incorrectly managed memory, resulting in\na memory leak.  If a user or automated system were tricked into \nprocessing a specially crafted input file, a remote attacker could\npossibly use this issue to cause a denial of service, or execute \narbitrary code.
