A new exploitation technique called key reinstallation attacks (KRACK) affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit this attack to decrypt Wi-Fi traffic or inject forged Wi-Fi packets by manipulating cryptograhpic handshakes used by the WPA2 protocol.

The host is installed with libXfixes 5.0 or earlier and is prone to an integer overflow vulnerability. A flaw is present in the application, which fails to properly handle crafted vectors related to the XFixesGetCursorImage function. Successful exploitation could allow attackers to lead to a heap-based buffer overflow.

The host is installed with libXext before 1.3.2 and is prone to multiple integer overflow vulnerabilities. The flaws are present in the application, which fails to handle vectors related to the (1) XcupGetReservedColormapEntries, (2) XcupStoreColors, (3) XdbeGetVisualInfo, (4) XeviGetVisualInfo, (5) XShapeGetRectangles, and (6) XSyncListSystemCounters functions. Successful exploitation could allow ...

The host is installed with libxslt before 1.1.28 and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to handle an empty match attribute in a XSL key to the xsltAddKey function in keys.c or uninitialized variable to the xsltDocumentFunction function in functions.c. Successful exploitation could allow attackers to crash the service.

The host is installed with libXv before 1.0.8 and is prone to multiple integer overflow vulnerabilities. The flaws are present in the application, which fails to handle crafted vectors related to the (1) XvQueryPortAttributes, (2) XvListImageFormats, and (3) XvCreateImage function. Successful exploitation could allow attackers to trigger allocation of insufficient memory and a buffer overflow.

The host is installed with libXv before 1.0.8 and is prone to multiple buffer overflow vulnerabilities. The flaws are present in the application, which fails to handle crafted length or index values. Successful exploitation could allow attackers to execute arbitrary code or crash the service.

The host is installed with libXinerama before 1.1.3 and is prone to an integer overflow vulnerability. A flaw is present in the application, which fails to handle crafted vectors related to the XineramaQueryScreens function. Successful exploitation could allow attackers to trigger allocation of insufficient memory and a buffer overflow.

The host is installed with libXcursor 1.1.13 and is prone to an integer overflow vulnerability. A flaw is present in the application, which fails to handle crafted vectors related to the _XcursorFileHeaderCreate function. Successful exploitation could allow attackers to trigger allocation of insufficient memory and a buffer overflow.

The host is installed with libXt before 1.1.4 and is prone to an array index error vulnerability. A flaw is present in the application, which fails to handle crafted length or index values to the _XtResourceConfigurationEH function. Successful exploitation could allow attackers to execute arbitrary code or crash the service.

The host is installed with libXt before 1.1.4 and is prone to a memory corruption vulnerability. A flaw is present in the application, which fails to properly handle unchecked function pointers. Successful exploitation could allow attackers to execute arbitrary code or crash the service.
