Avatud on teave kahe haavatavuse kohta FFmpeg paketis tarnitud JPEG XL formaadi dekooderis, mis v\u00f5ivad v\u00f5imaldada pahatahtliku koodi t\u00e4itmist, kui FFmpeg t\u00f6\u00f6tleb spetsiaalselt vormindatud pilte. Probleemid on lahendatud FFmpeg 6.1 versioonis, kuid kuna JPEG XL tugi on lisatud alates 6.1 harust, m\u00f5jutab haavatavus ainult s\u00fcsteeme, mis kasutavad katsetavaid FFmpeg 6.1 ehitusi v\u00f5i edastavad neist muudatusi. <\/p>\n

Esimene haavatavus (CVE-2024-22860) on p\u00f5hjustatud t\u00e4isarvu \u00fclevoolust JPEG XL formaadi parseris, mis on tekkinud int t\u00fc\u00fcpi suuruse \u00fclemise piiri kontrolli puudumise t\u00f5ttu. Teine haavatavus (CVE-2024-22862) ilmnes t\u00e4isarvude \u00fclevoolust jpegxl_anim_read_packet funktsioonis, mida kasutatakse animaatsiooni dekodeerimiseks ja on seotud signeeritud int64_t t\u00fc\u00fcbi asemel signeerimata uint64_t kasutamisega. Probleemid on spetsiifilised FFmpegile ega avaldu viidatud libjxl rakenduses.
