CVE-2004-0688 4 Openbsd, Suse, X.org and 1 more 4 Openbsd, Suse Linux, X11r6 and 1 more 2025-04-03 7.5 HIGH N/A
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 execute arbitrary code via a malformed XPM image file.

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 vulnerability than CVE-2004-0084 and CVE-2004-0106.
CVE-1999-0241 3 Sgi, Sun, Xfree86 Project 4 Irix, Solaris, Sunos and 1 more 2025-04-03 10.0 HIGH N/A
Guessable magic cookies in X Windows allows remote attackers to execute commands, e.g. through xterm.
CVE-2003-0071 1 Xfree86 Project 1 X11r6 2025-04-03 2.1 LOW N/A
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 tight loop.
CVE-2005-0605 8 Altlinux, Lesstif, Mandrakesoft and 5 more 11 Alt Linux, Lesstif, Mandrake Linux and 8 more 2025-04-03 7.5 HIGH N/A
scan.c for LibXPM may allow attackers to execute arbitrary code via a negative bitmap_unit value that leads to a buffer overflow.
CVE-2000-0504 3 Gnome, Open Group, Xfree86 Project 3 Gdm, X, X11r6 2025-04-03 5.0 MEDIUM N/A
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.
CVE-2000-0476 4 Michael Jennings, Putty, Rxvt and 1 more 4 Eterm, Putty, Rxvt and 1 more 2025-04-03 5.0 MEDIUM N/A
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.
CVE-2000-0620 2 Open Group, Xfree86 Project 2 X, X11r6 2025-04-03 5.0 MEDIUM N/A
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.
CVE-2003-0063 1 Xfree86 Project 1 X11r6 2025-04-03 7.5 HIGH 7.3 HIGH
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. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands.
CVE-2004-0084 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2025-04-03 10.0 HIGH N/A
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 font alias (font.alias) file, a different vulnerability than CVE-2004-0083 and CVE-2004-0106.
CVE-2002-1317 4 Hp, Sgi, Sun and 1 more 5 Hp-ux, Irix, Solaris and 2 more 2025-04-03 7.5 HIGH N/A
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.
CVE-2004-0914 6 Gentoo, Lesstif, Redhat and 3 more 6 Linux, Lesstif, Fedora Core and 3 more 2025-04-03 10.0 HIGH N/A
Multiple vulnerabilities in libXpm for 6.8.1 and earlier, as used in XFree86 and other packages, include (1) multiple integer overflows, (2) out-of-bounds memory accesses, (3) directory traversal, (4) shell metacharacter, (5) endless loops, and (6) memory leaks, which could allow remote attackers to obtain sensitive information, cause a denial of service (application crash), or execute arbitrary code via a certain XPM image file. NOTE: it is highly likely that this candidate will be SPLIT into other candidates in the future, per CVE's content decisions.
