Problemerne er blevet l\u00f8st i versionerne libXpm 3.5.17 og libX11 1.8.7. Tre s\u00e5rbarheder er identificeret i bibliotektet libx11, der tilbyder funktioner med klientimplementering af X11-protokollen:   <\/p>\n<ul>\n<li class=\"l\"> CVE-2023-43785 \u2014 buffer overflow in the libX11 code, occurring when processing a response from the X server with a number of characters that does not match the previously sent request XkbGetMap. The vulnerability is caused by an error in X11R6.1, which has existed since 1996. It can be exploited when an application using libx11 connects to a malicious X server or an intermediary proxy controlled by an attacker.\n<li class=\"l\"> CVE-2023-43786 \u2014 stack exhaustion due to infinite recursion in the PutSubImage() function in libX11, occurring when processing specially crafted XPM formatted data. This vulnerability has existed since the release of X11R2 in February 1988.\n<li class=\"l\"> CVE-2023-43787 \u2014 integer overflow in the XCreateImage() function in libX11, leading to heap overflow due to incorrect size calculation that does not match the actual size of the data. The problematic function XCreateImage() is called from the XpmReadFileToPixmap() function, allowing exploitation of the vulnerability when processing a specially crafted file in XPM format. This vulnerability has also existed since X11R2 (1988).    <\/ul>\n<p>Derudover er der blevet afsl\u00f8ret to s\u00e5rbarheder i biblioteket libXpm (CVE-2023-43788 og CVE-2023-43789), for\u00e5rsaget af muligheden for at l\u00e6se fra omr\u00e5der uden for gr\u00e6nserne af den tildelte hukommelse. Problemerne opst\u00e5r ved indl\u00e6sning af en kommentar fra hukommelsesbufferen og behandling af en XPM-fil med et ugyldigt farvekort. Begge s\u00e5rbarheder dateres tilbage til 1998 og blev fundet takket v\u00e6re brugen af v\u00e6rkt\u00f8jer til at opdage hukommelsesfejl og fuzzing-testning af AddressSanitizer og libFuzzer.        <\/p>\n<p>X.org har historiske sikkerhedsproblemer, for eksempel for ti \u00e5r siden, p\u00e5 den 30. konference for Chaos Communication Congress (CCC), blev halvdelen af pr\u00e6sentationen af sikkerhedsforskeren Ilja van Sprundel dedikeret til problemerne i <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/dts-newyork\/\"   title=\"serveren\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2764\">serveren<\/a> X.Org and the other half of the security of client libraries for X11.
