2020-08-05 CVE-2020-14344 An integer overflow leading to a heap-buffer overflow was found in The X Input Method (XIM) client was implemented in libX11 before version 1.6.10. As per upstream this is security relevant when setuid programs call XIM client functions while running with elevated privileges. No such programs are shipped with Red Hat Enterprise Linux. Ubuntu_linux, Fedora, Leap, Libx11 6.7
2020-09-11 CVE-2020-14363 An integer overflow vulnerability leading to a double-free was found in libX11. This flaw allows a local privileged attacker to cause an application compiled with libX11 to crash, or in some cases, result in arbitrary code execution. The highest threat from this flaw is to confidentiality, integrity as well as system availability. Fedora, Libx11 7.8
2021-05-27 CVE-2021-31535 LookupCol.c in X.Org X through X11R7.7 and libX11 before 1.7.1 might allow remote attackers to execute arbitrary code. The libX11 XLookupColor request (intended for server-side color lookup) contains a flaw allowing a client to send color-name requests with a name longer than the maximum size allowed by the protocol (and also longer than the maximum packet size for normal-sized packets). The user-controlled data exceeding the maximum size is then interpreted by the server as additional X... Fedora, Libx11, X_window_system 9.8
2018-08-24 CVE-2018-14600 An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading to DoS or remote code execution. Ubuntu_linux, Debian_linux, Libx11 9.8
2018-08-24 CVE-2018-14599 An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other impact. Ubuntu_linux, Debian_linux, Fedora, Libx11 9.8
2018-08-24 CVE-2018-14598 An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault). Ubuntu_linux, Debian_linux, Fedora, Libx11 7.5
2015-04-16 CVE-2013-7439 Multiple off-by-one errors in the (1) MakeBigReq and (2) SetReqLen macros in include/X11/Xlibint.h in X11R6.x and libX11 before 1.6.0 allow remote attackers to have unspecified impact via a crafted request, which triggers a buffer overflow. Ubuntu_linux, Debian_linux, Libx11, X11 N/A
