Multiple integer overflows in (1) the xpmParseColors function in parse.c, (2) XpmCreateImageFromXpmImage, (3) CreateXImage, (4) ParsePixels, and (5) ParseAndPutPixels for libXpm before 6.8.1 may allow remote attackers to…

Multiple stack-based buffer overflows in (1) xpmParseColors in parse.c, (2) ParseAndPutPixels in create.c, and (3) ParsePixels in parse.c for libXpm before 6.8.1 allow remote attackers to execute arbitrary code via a mal…

Integer signedness errors in XFree86 4.1.0 allow remote attackers to cause a denial of service and possibly execute arbitrary code when using the GLX extension and Direct Rendering Infrastructure (DRI).

XFree86 4.1.0 allows remote attackers to cause a denial of service and possibly execute arbitrary code via an out-of-bounds array index when using the GLX extension and Direct Rendering Infrastructure (DRI).

The DEC UDK processing feature in the xterm terminal emulator in XFree86 4.2.99.4 and earlier allows attackers to cause a denial of service via a certain character escape sequence that causes the terminal to enter a tigh…

The xterm terminal emulator in XFree86 4.2.0 and earlier allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g.

xdm, with the authComplain variable set to false, allows arbitrary attackers to connect to the X server if the xdm auth directory does not exist.

Untrusted search path vulnerability in libX11.so in xfree86, when used in setuid or setgid programs, allows local users to gain root privileges via a modified LD_PRELOAD environment variable that points to a malicious mo…

Buffer overflow in Dispatch() routine for XFS font server (fs.auto) on Solaris 2.5.1 through 9 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a certain XFS query.

Multiple unknown vulnerabilities in XFree86 4.1.0 to 4.3.0, related to improper handling of font files, a different set of vulnerabilities than CVE-2004-0083 and CVE-2004-0084.

Buffer overflow in the ReadFontAlias function in XFree86 4.1.0 to 4.3.0, when using the CopyISOLatin1Lowered function, allows local or remote authenticated users to execute arbitrary code via a malformed entry in the fon…

Buffer overflow in ReadFontAlias from dirfile.c of XFree86 4.1.0 through 4.3.0 allows local users and remote attackers to execute arbitrary code via a font alias file (font.alias) with a long token, a different vulnerabi…

Multiple integer overflows in the font libraries for XFree86 4.3.0 allow local or remote attackers to cause a denial of service or execute arbitrary code via heap-based and stack-based buffer overflow attacks.

xman allows local users to gain privileges by modifying the MANPATH to point to a man page whose filename contains shell metacharacters.

Buffer overflow in xman allows local users to gain privileges via a long MANPATH environment variable.

XDM in XFree86 3.3 and 3.3.3 generates easily guessable cookies using gettimeofday() when compiled with the HasXdmXauth option, which allows remote attackers to gain unauthorized access to the X display via a brute force…

Buffer overflow in fbglyph.c in XFree86 before 4.2.0, related to glyph clipping for large origins, allows attackers to cause a denial of service and possibly gain privileges via a large number of characters, possibly thr…

libX11 X library allows remote attackers to cause a denial of service via a resource mask of 0, which causes libX11 to go into an infinite loop.

libICE in XFree86 allows remote attackers to cause a denial of service by specifying a large value which is not properly checked by the SKIP_STRING macro.

Buffer overflow in XFree86 3.3.x allows local users to execute arbitrary commands via a long -xkbmap parameter.

xterm, Eterm, and rxvt allow an attacker to cause a denial of service by embedding certain escape characters which force the window to be resized.

XFree86 3.3.x and 4.0 allows a user to cause a denial of service via a negative counter value in a malformed TCP packet that is sent to port 6000.
