Gstreamer1-plugins-bad-free: gstreamer: stack buffer overflow in h.265 buffering period sei parser
Vulnerability Description
A stack buffer overflow flaw was found in the GStreamer H.265 codec parser library (gst-plugins-bad). When parsing a buffering period SEI message, the parser uses an incorrect loop bound derived from cpb_cnt_minus1[i] (the loop index) instead of the sub-layer 0 CPB count cpb_cnt_minus1[0] from the referenced Sequence Parameter Set. A crafted H.265 video file or stream can cause the parser to write beyond the bounds of stack-allocated CPB delay arrays, resulting in a crash or potential stack memory corruption.

gst-plugins-bad 缓冲区错误漏洞
Vulnerability Description
gst-plugins-bad是GStreamer开源的一个GStreamer插件。 gst-plugins-bad存在缓冲区错误漏洞,该漏洞源于H.265编解码器解析器库在解析缓冲期SEI消息时使用错误的循环边界,导致写入栈分配的CPB延迟数组边界之外,精心构造的H.265视频文件或流可能导致崩溃或栈内存损坏。
