Informatie over vijf kwetsbaarheden in de bibliotheken libX11 en libXpm, ontwikkeld door het X.Org-project, is bekendgemaakt. De problemen zijn verholpen in de versies libXpm 3.5.17 en libX11 1.8.7. Drie kwetsbaarheden zijn ontdekt in de bibliotheek libX11, die functies biedt met een clientimplementatie van het X11-protocol: <\/p>\n
Bovendien zijn er twee kwetsbaarheden in de bibliotheek libXpm onthuld (CVE-2023-43788 en CVE-2023-43789), veroorzaakt door de mogelijkheid om te lezen uit gebieden buiten de grenzen van toegewezen geheugen. De problemen doen zich voor bij het laden van een commentaar uit een buffer in het geheugen en het verwerken van een XPM-bestand met een onjuiste kleurenkaart. Beide kwetsbaarheden dateren uit 1998 en zijn ontdekt door het gebruik van tools voor het opsporen van geheugenfouten en fuzzing-testen zoals AddressSanitizer en libFuzzer. <\/p>\n
X.org heeft historische beveiligingsproblemen; bijvoorbeeld tien jaar geleden, op de 30e conferentie van de Chaos Communication Congress (CCC), was in de presentatie van beveiligingsonderzoeker Ilja van Sprundel de helft gewijd aan problemen in de server<\/a> X.Org, and the other half concerns the security of client libraries of X11. In Ilya's report, which identified 30 vulnerabilities affecting various X11 client libraries and Mesa DRI components in 2013, there were emotional statements such as \u2018GLX \u2014 a terrible demotivator! 80,000 lines of pure horror!\u2019 and \u2018In the last couple of months, I found 120 bugs in it, and I'm not done checking yet.\u2019 \u041e\u0431\u043d\u0430\u0440\u043e\u0434\u043e\u0432\u0430\u043d\u0430 \u0438\u043d\u0444\u043e\u0440\u043c\u0430\u0446\u0438\u044f \u043e \u043f\u044f\u0442\u0438 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044f\u0445 \u0432 \u0431\u0438\u0431\u043b\u0438\u043e\u0442\u0435\u043a\u0430\u0445 libX11 \u0438 libXpm, \u0440\u0430\u0437\u0432\u0438\u0432\u0430\u0435\u043c\u044b\u0445 \u043f\u0440\u043e\u0435\u043a\u0442\u043e\u043c X.Org. \u041f\u0440\u043e\u0431\u043b\u0435\u043c\u044b \u0443\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u044b \u0432 \u0432\u044b\u043f\u0443\u0441\u043a\u0430\u0445 libXpm 3.5.17 \u0438 libX11 1.8.7. \u0422\u0440\u0438 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0438 \u0432\u044b\u044f\u0432\u043b\u0435\u043d\u044b \u0432 \u0431\u0438\u0431\u043b\u0438\u043e\u0442\u0435\u043a\u0435 libx11, \u043f\u0440\u0435\u0434\u043b\u0430\u0433\u0430\u044e\u0449\u0435\u0439 \u0444\u0443\u043d\u043a\u0446\u0438\u0438 \u0441 \u043a\u043b\u0438\u0435\u043d\u0442\u0441\u043a\u043e\u0439 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0435\u0439 \u043f\u0440\u043e\u0442\u043e\u043a\u043e\u043b\u0430 X11: CVE-2023-43785 — \u0432\u044b\u0445\u043e\u0434 \u0437\u0430 \u0433\u0440\u0430\u043d\u0438\u0446\u044b \u0431\u0443\u0444\u0435\u0440\u0430 \u0432 \u043a\u043e\u0434\u0435 libX11, \u043f\u0440\u043e\u044f\u0432\u043b\u044f\u044e\u0449\u0438\u0439\u0441\u044f \u043f\u0440\u0438 \u043e\u0431\u0440\u0430\u0431\u043e\u0442\u043a\u0435 \u043e\u0442\u0432\u0435\u0442\u0430 \u043e\u0442 X-\u0441\u0435\u0440\u0432\u0435\u0440\u0430 \u0441 \u0447\u0438\u0441\u043b\u043e\u043c \u0441\u0438\u043c\u0432\u043e\u043b\u043e\u0432, \u043d\u0435 \u0441\u043e\u043e\u0442\u0432\u0435\u0442\u0441\u0442\u0432\u0443\u044e\u0449\u0438\u0445 […]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-110740","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\n","aioseo_head_json":{"title":"\ud83e\udd47Kwetsbaarheden in de bibliotheken X.Org, waarvan twee sinds 1988 bestaan | ProHoster","description":"Informatie is gepubliceerd over vijf kwetsbaarheden in de bibliotheken libX11 en libXpm, ontwikkeld door het X.Org-project.
