CVSS v3.1 |
| 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 through the web page search form of KDE Konqueror or from an xterm command with a long title. |
| SGI IRIX buffer overflow in xterm and Xaw allows root access. |
| Guessable magic cookies in X Windows allows remote attackers to execute commands, e.g. through xterm. |
| XFree86 startx command is vulnerable to a symlink attack, allowing local users to create files in restricted directories, possibly allowing them to gain privileges or cause a denial of service. |
| Buffer overflow in xman allows local users to gain privileges via a long MANPATH environment variable. |
| 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. |
| 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. |
| xman allows local users to gain privileges by modifying the MANPATH to point to a man page whose filename contains shell metacharacters. |
| scan.c for LibXPM may allow attackers to execute arbitrary code via a negative bitmap_unit value that leads to a buffer overflow. |
| 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 attack. |
| Integer overflow in the ProcDbeSwapBuffers 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. |
| 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. |
| Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 20070403 and (2) freetype 2.3.2 and earlier allows remote authenticated users to execute arbitrary code via crafted BDF fonts, which result in a heap overflow. |
| Array index error in the XFree86-Misc extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via a PassMessage request containing a large array index. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Buffer overflow in xlib in XFree 3.3.x possibly allows local users to execute arbitrary commands via a long DISPLAY environment variable or a -display command line parameter. |
