Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 FFmpeg 8.1.3 之前的版本以及 9.x 系列中 9.0.2 之前的版本中， 文件中的 函数存在越界读取漏洞。当 NaN（非数字）样本导致码本条目值为 -1 时，该漏洞会被触发。攻击者可向原生 Vorbis 编码器提供包含 NaN 浮点样本的音频数据，从而引发在数组之前的堆内存读取操作，导致应用程序崩溃，或将相邻的堆内存泄露到输出文件中。

FFmpeg before 8.1.3 and 9.x before 9.0.2 Out-of-Bounds Read in Vorbis Encoder
Source: CVE Program / CVE List V5
Vulnerability Description
FFmpeg before 8.1.3 and 9.x before 9.0.2 contains an out-of-bounds read vulnerability in put_vector() in libavcodec/vorbisenc.c when NaN samples leave the codebook entry at -1. Attackers can supply audio with NaN float samples to the native Vorbis encoder, causing heap reads before arrays that crash the application or leak adjacent heap memory into output.
