Libtheora: libtheora: denial of service or information disclosure via malformed avi file processing

A flaw was found in libtheora. This heap-based out-of-bounds read vulnerability exists within the AVI (Audio Video Interleave) parser, specifically in the avi_parse_input_file() function. A local attacker could exploit this by tricking a user into opening a specially crafted AVI file containing a truncated header sub-chunk. This could lead to a denial-of-service (application crash) or potentially leak sensitive information from the heap.

跨界内存读

Theora 缓冲区错误漏洞

Theora是Xiph开源的一个 Theora 视频压缩格式的参考实现。 Theora存在缓冲区错误漏洞，该漏洞源于AVI解析器中avi_parse_input_file函数存在堆越界读取，可能导致拒绝服务或堆敏感信息泄露。
