Integer overflow in the ProcDbeGetVisualInfo function in the DBE extension for X.Org 6.8.2, 6.9.0, 7.0, and 7.1, and XFree86 X server, allows local users to execute arbitrary code via a crafted X protocol request that triggers memory corruption during processing of unspecified data structures.
CVE-2007-4990 1 X.org 1 X Font Server 2023-12-10 7.5 HIGH N/A
The swap_char2b function in X.Org X Font Server (xfs) before 1.0.5 allows context-dependent attackers to execute arbitrary code via (1) QueryXBitmaps and (2) QueryXExtents protocol requests with crafted size values that specify an arbitrary number of bytes to be swapped on the heap, which triggers heap corruption.
CVE-2007-6427 7 Apple, Canonical, Debian and 4 more 11 Mac Os X, Ubuntu Linux, Debian Linux and 8 more 2023-12-10 9.3 HIGH N/A
The XInput extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via requests related to byte swapping and heap corruption within multiple functions, a different vulnerability than CVE-2007-4990.
CVE-2007-1667 2 Imagemagick, X.org 2 Imagemagick, Libx11 2023-12-10 9.3 HIGH N/A
Multiple integer overflows in (1) the XGetPixel function in ImUtil.c in X.Org libx11 before 1.0.3, and (2) XInitImage function in xwd.c for ImageMagick, allow user-assisted remote attackers to cause a denial of service (crash) or obtain sensitive information via crafted images with large or negative values that trigger a buffer overflow.
CVE-2007-1352 8 Mandrakesoft, Openbsd, Redhat and 5 more 14 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 11 more 2023-12-10 3.8 LOW N/A
Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow.
CVE-2007-6429 1 X.org 3 Evi, Mit-shm, Xserver 2023-12-10 9.3 HIGH N/A
Multiple integer overflows in X.Org Xserver before 1.4.1 allow context-dependent attackers to execute arbitrary code via (1) a GetVisualInfo request containing a 32-bit value that is improperly used to calculate an amount of memory for allocation by the EVI extension, or (2) a request containing values related to pixmap size that are improperly used in management of shared memory by the MIT-SHM extension.
CVE-2007-4568 1 X.org 1 X Font Server 2023-12-10 6.8 MEDIUM N/A
Integer overflow in the build_range function in X.Org X Font Server (xfs) before 1.0.5 allows context-dependent attackers to execute arbitrary code via (1) QueryXBitmaps and (2) QueryXExtents protocol requests with crafted size values, which triggers a heap-based buffer overflow.
CVE-2006-5397 1 X.org 1 Libx11 2023-12-10 2.1 LOW N/A
The Xinput module (modules/im/ximcp/imLcIm.c) in X.Org libX11 1.0.2 and 1.0.3 opens a file for reading twice using the same file descriptor, which causes a file descriptor leak that allows local users to read files specified by the XCOMPOSEFILE environment variable via the duplicate file descriptor.
CVE-2006-5215 3 Netbsd, Sun, X.org 4 Netbsd, Solaris, Sunos and 1 more 2023-12-10 2.6 LOW N/A
The Xsession script, as used by X Display Manager (xdm) in NetBSD before 20060212, X.Org before 20060317, and Solaris 8 through 10 before 20061006, allows local users to overwrite arbitrary files, or read another user's Xsession errors file, via a symlink attack on a /tmp/xses-$USER file.
CVE-2008-0006 2 Sun, X.org 3 Solaris Libfont, Solaris Libxfont, Xserver 2023-12-10 7.5 HIGH N/A
Buffer overflow in (1) X.Org Xserver before 1.4.1, and (2) the libfont and libXfont libraries on some platforms including Sun Solaris, allows context-dependent attackers to execute arbitrary code via a PCF font with a large difference between the last col and first col values in the PCF_BDF_ENCODINGS table.
CVE-2006-6101 2 X.org, Xfree86 Project 2 X.org, Xfree86 2023-12-10 6.6 MEDIUM N/A
Integer overflow in the ProcRenderAddGlyphs function in the Render extension for X.Org 6.8.2, 6.9.0, 7.0, and 7.1, and XFree86 X server, allows local users to execute arbitrary code via a crafted X protocol request that triggers memory corruption during processing of glyph management data structures.
CVE-2006-1526 1 X.org 1 X11r6 2023-12-10 2.1 LOW N/A
Buffer overflow in the X render (Xrender) extension in X.org X server 6.8.0 up to allows attackers to cause a denial of service (crash), as demonstrated by the (1) XRenderCompositeTriStrip and (2) XRenderCompositeTriFan requests in the rendertest from XCB xcb/xcb-demo, which leads to an incorrect memory allocation due to a typo in an expression that uses a "&" instead of a "*" operator. NOTE: the subject line of the original announcement used an incorrect CVE number for this issue.
CVE-2006-0745 5 Mandrakesoft, Redhat, Sun and 2 more 6 Mandrake Linux, Fedora Core, Solaris and 3 more 2023-12-10 7.2 HIGH N/A
X.Org server (xorg-server) 1.0.0 and later, X11R6.9.0, and X11R7.0 inadvertently treats the address of the geteuid function as if it is the return value of a call to geteuid, which allows local users to bypass intended restrictions and (1) execute arbitrary code via the -modulepath command line option or (2) overwrite arbitrary files via -logfile.
CVE-2005-0605 8 Altlinux, Lesstif, Mandrakesoft and 5 more 11 Alt Linux, Lesstif, Mandrake Linux and 8 more 2023-12-10 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-2006-0197 1 X.org 1 X.org 2023-12-10 5.0 MEDIUM N/A
The XClientMessageEvent struct used in certain components of X.Org 6.8.2 and earlier, possibly including (1) the X server and (2) Xlib, uses a "long" specifier for elements of the l array, which results in inconsistent sizes in the struct on 32-bit versus 64-bit platforms, and might allow attackers to cause a denial of service (application crash) and possibly conduct other attacks.
CVE-2006-3740 2 X.org, Xfree86 Project 2 X.org, Xfree86 X 2023-12-10 7.2 HIGH N/A
Integer overflow in the scan_cidfont function in X.Org 6.8.2 and XFree86 X server allows local users to execute arbitrary code via crafted (1) CMap and (2) CIDFont font data with modified item counts in the (a) begincodespacerange, (b) cidrange, and (c) notdefrange sections.
CVE-2006-3739 2 X.org, Xfree86 Project 2 X.org, Xfree86 X 2023-12-10 7.2 HIGH N/A
Integer overflow in the CIDAFM function in X.Org 6.8.2 and XFree86 X server allows local users to execute arbitrary code via crafted Adobe Font Metrics (AFM) files with a modified number of character metrics (StartCharMetrics), which leads to a heap-based buffer overflow.
CVE-2006-4447 1 X.org 9 Emu-linux-x87-xlibs, X11r6, X11r7 and 6 more 2023-12-10 7.2 HIGH N/A
X.Org and XFree86, including libX11, xdm, xf86dga, xinit, xload, xtrans, and xterm, does not check the return values for setuid and seteuid calls when attempting to drop privileges, which might allow local users to gain privileges by causing those calls to fail, such as by exceeding a ulimit.
CVE-2004-0914 6 Gentoo, Lesstif, Redhat and 3 more 6 Linux, Lesstif, Fedora Core and 3 more 2023-12-10 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.
CVE-2004-0419 3 Gentoo, X.org, Xfree86 Project 3 Linux, X11r6, Xdm 2023-12-10 7.5 HIGH N/A
XDM in XFree86 opens a chooserFd TCP socket even when DisplayManager.requestPort is 0, which could allow remote attackers to connect to the port, in violation of the intended restrictions.
