Quick assessment

Affected
n/a GPAC
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.

GPAC Project Advanced Content是MPEG-4系统标准的实现，以ANSI C编写。 GPAC Project Advanced Content存在缓冲区错误漏洞，该漏洞源于 Advanced Content 的 MPEG-4 解码功能中存在多个可利用的整数溢出漏洞。特制的 MPEG-4 文件输入可能会由于未经检查的加法运算导致整数溢出，从而导致基于堆的缓冲区溢出，从而导致内存损坏。攻击者可以诱使用户打开视频以触发此漏洞。
