libXcursor before 1.1.15 has various integer overflows that could lead to heap buffer overflows when processing malicious cursors, e.g., with programs like GIMP. It is also possible that an attack vector exists against the related code in cursor/xcursor.c in Wayland through 1.14.0.
CVE-2014-0210 2 Canonical, X 2 Ubuntu Linux, Libxfont 2025-04-12 7.5 HIGH N/A
Multiple buffer overflows in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs protocol reply to the (1) _fs_recv_conn_setup, (2) fs_read_open_font, (3) fs_read_query_info, (4) fs_read_extent_info, (5) fs_read_glyphs, (6) fs_read_list, or (7) fs_read_list_info function.
CVE-2014-0209 2 Canonical, X 2 Ubuntu Linux, Libxfont 2025-04-12 4.6 MEDIUM N/A
Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 might allow local users to gain privileges by adding a directory with a large fonts.dir or fonts.alias file to the font path, which triggers a heap-based buffer overflow, related to metadata.

The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly perform type conversion for metrics values, which allows remote authenticated users to cause a denial of service (out-of-bounds memory access) and possibly execute arbitrary code via a crafted BDF font file.
CVE-2016-7951 2 Fedoraproject, X 2 Fedora, Libxtst 2025-04-12 7.5 HIGH 9.8 CRITICAL
Multiple integer overflows in X.org libXtst before 1.2.3 allow remote X servers to trigger out-of-bounds memory access operations by leveraging the lack of range checks.
CVE-2014-0211 2 Canonical, X 2 Ubuntu Linux, Libxfont 2025-04-12 7.5 HIGH N/A
Multiple integer overflows in the (1) fs_get_reply, (2) fs_alloc_glyphs, and (3) fs_read_extent_info functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 allow remote font servers to execute arbitrary code via a crafted xfs reply, which triggers a buffer overflow.
CVE-2014-4910 1 X 1 Xf86-video-intel 2025-04-12 4.6 MEDIUM N/A
Directory traversal vulnerability in tools/backlight_helper.c in X.Org xf86-video-intel 2.99.911 allows remote attackers to create or overwrite arbitrary files via a .. (dot dot) in the interface name.
CVE-2015-1802 3 Canonical, Debian, X 3 Ubuntu Linux, Debian Linux, Libxfont 2025-04-12 8.5 HIGH N/A
The bdfReadProperties function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 allows remote authenticated users to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a (1) negative or (2) large property count in a BDF font file.
CVE-2015-1803 3 Canonical, Debian, X 3 Ubuntu Linux, Debian Linux, Libxfont 2025-04-12 8.5 HIGH N/A
The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly handle character bitmaps it cannot read, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a crafted BDF font file.
CVE-2013-2005 1 X 1 Libxt 2025-04-11 6.8 MEDIUM N/A
X.org libXt 1.1.3 and earlier does not check the return value of the XGetWindowProperty function, which allows X servers to trigger use of an uninitialized pointer and memory corruption via vectors related to the (1) ReqCleanup, (2) HandleSelectionEvents, (3) ReqTimedOut, (4) HandleNormal, and (5) HandleSelectionReplies functions.
CVE-2013-2062 1 X 1 Libxp 2025-04-11 6.8 MEDIUM N/A
