Description

This security bulletin contains information about 1 vulnerability.


1) Infinite loop (CVE-ID: CVE-2017-14058)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

In FFmpeg 3.3.3, the read_data function in libavformat/hls.c does not restrict reload attempts for an insufficient list, which allows remote attackers to cause a denial of service (infinite loop).
