脆弱性タイトル
Gstreamer1-plugins-bad-free: gstreamer: heap buffer overflow via crafted vnc server rectangle in librfb
ソース: NVD (National Vulnerability Database)
脆弱性説明
A heap buffer overflow vulnerability was found in GStreamer's librfb (RFB/VNC client). The rectangle bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a malicious VNC server and trick a user into connecting, resulting in an out-of-bounds heap write that could lead to code execution or a crash.

脆弱性タイプ
堆缓冲区溢出
ソース: NVD (National Vulnerability Database)
脆弱性タイトル
GStreamer 缓冲区错误漏洞
ソース: CNNVD (China National Vulnerability Database)
脆弱性説明
GStreamer是GStreamer组织开源的一套用于处理流媒体的框架。 GStreamer存在缓冲区错误漏洞，该漏洞源于矩形边界检查错误验证区域而非单个维度，可能导致恶意VNC服务器发送超出帧缓冲区的矩形，造成堆越界写入，从而导致代码执行或崩溃。
