MGASA-2024-0186 - Updated stb packages fix security vulnerabilities

Publication date: 21 May 2024
URL: https://advisories.mageia.org/MGASA-2024-0186.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2023-45681,
     CVE-2023-47212

stb_vorbis is a single file MIT licensed library for processing ogg
vorbis files. A crafted file may trigger memory write past an allocated
heap buffer in `start_decoder`. The root cause is a potential integer
overflow in `sizeof(char*) * (f->comment_list_length)` which may make
`setup_malloc` allocate less memory than required. Since there is
another integer overflow an attacker may overflow it too to force
`setup_malloc` to return 0 and make the exploit more reliable. This
issue may lead to code execution.
