安全等级: High
公告ID: KylinSec-SA-2024-3239
发布日期: 2024年7月19日
FFmpeg is a complete and free Internet live audio and video broadcasting solution for Linux/Unix. It also includes a digital VCR. It can encode in real time in many formats including MPEG1 audio and video, MPEG4, h263, ac3, asf, avi, real, mjpeg, and flash.
Security Fix(es):
An integer overflow vulnerability was found in FFmpeg versions before 4.4.2 and before 5.0.1 in g729_parse() in llibavcodec/g729_parser.c when processing a specially crafted file.(CVE-2022-1475)
libavcodec/pthread_frame.c in FFmpeg before 5.1.2, as used in VLC and other products, leaves stale hwaccel state in worker threads, which allows attackers to trigger a use-after-free and execute arbitrary code in some circumstances (e.g., hardware re-initialization upon a mid-video SPS change when Direct3D11 is used).(CVE-2022-48434)
FFmpeg 7.0 is vulnerable to Buffer Overflow. There is a negative-size-param bug at libavcodec/mpegvideo_enc.c:1216:21 in load_input_picture in FFmpeg7.0(CVE-2024-32230)
