Ubuntu Security Notice 6408-2 - USN-6408-1 fixed several vulnerabilities in libXpm. This update provides the corresponding update for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. Yair Mizrahi discovered that libXpm incorrectly handled certain malformed XPM image files. If a user were tricked into opening a specially crafted XPM image file, a remote attacker could possibly use this issue to consume memory, leading to a denial of service.

A vulnerability was found in libX11 due to a boundary condition within the _XkbReadKeySyms() function. This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system.

A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges.

A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition.

Debian Linux Security Advisory 5517-1 - Multiple security vulnerabilities were discovered in libx11, the X11 client-side library, which may result in denial of service or the execution of arbitrary code.

A vulnerability was found in libX11. The security flaw occurs because the functions in src/InitExt.c in libX11 do not check that the values provided for the Request, Event, or Error IDs are within the bounds of the arrays that those functions write to, using those IDs as array indexes. They trust that they were called with values provided by an Xserver adhering to the bounds specified in the X11 protocol, as all X servers provided by X.Org do. As the protocol only specifies a single byte for these values, an out-of-bounds value provided by a malicious server (or a malicious proxy-in-the-middle) can only overwrite other portions of the Display structure and not write outside the bounds of the Display structure itself, possibly causing the client to crash with this memory corruption.

Dell VxRail, version(s) 8.0.100 and earlier contain a denial-of-service vulnerability in the upgrade functionality. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to degraded performance and system malfunction.

Debian Linux Security Advisory 5433-1 - Gregory James Duck reported that missing input validation in various functions provided by libx11, the X11 client-side library, may result in denial of service.
