Informa\u021biile despre cinci vulnerabilit\u0103\u021bi \u00een bibliotecile libX11 \u0219i libXpm, care sunt dezvoltate de proiectul X.Org, au fost publicate. Problemele au fost remediate \u00een versiunile libXpm 3.5.17 \u0219i libX11 1.8.7. Trei vulnerabilit\u0103\u021bi au fost identificate \u00een biblioteca libX11, care ofer\u0103 func\u021bionalit\u0103\u021bi cu implementare client pentru protocolul X11: <\/p>\n
\u00cen plus, au fost descoperite dou\u0103 vulnerabilit\u0103\u021bi \u00een biblioteca libXpm (CVE-2023-43788 \u0219i CVE-2023-43789), cauzate de posibilitatea de a citi din zonele \u00een afara limitelor memoriei alocate. Problemele apar \u00een timpul \u00eenc\u0103rc\u0103rii comentariilor din buffer-ul de memorie \u0219i proces\u0103rii unui fi\u0219ier XPM cu o hart\u0103 de culori incorect\u0103. Ambele vulnerabilit\u0103\u021bi dateaz\u0103 din 1998 \u0219i au fost identificate prin utilizarea instrumentelor de depanare a memoriei \u0219i testarea fuzzing cu AddressSanitizer \u0219i libFuzzer. <\/p>\n
