CWE ID 476


CVE-2023-45680 is a vulnerability affecting the stb_vorbis library, a single file MIT licensed library used for processing ogg vorbis files. The vulnerability occurs when a crafted file triggers a memory allocation failure in the start_decoder function, leading to a denial of service. This issue occurs because the f->comment_list is set to NULL but f->comment_list_length is not reset. As a result, when the vorbis_deinit function tries to dereference the NULL pointer, it can potentially cause the application to crash or become unresponsive. This vulnerability has a base severity of MEDIUM and an exploitability score of 3.9 out of 10, indicating that it poses a moderate risk to organizations using the affected library. To remediate this vulnerability, users should update their stb_vorbis library to a version that includes a fix for this issue.
