USN-3583-1: Linux kernel vulnerabilities

It was discovered that an out-of-bounds write vulnerability existed in the Flash-Friendly File System f2fs in the Linux kernel. An attacker could construct a malicious file system that, when mounted, could cause a denial of service system crash or possibly execute arbitrary code. CVE-2017-0750 It...

DEBIAN-CVE-2018-6412

In the function sbusfbioctlhelper in drivers/video/fbdev/sbuslib.c in the Linux kernel through 4.15, an integer signedness error allows arbitrary information leakage for the FBIOPUTCMAPSPARC and FBIOGETCMAPSPARC commands...

Design/Logic Flaw

VNC server implementation in Quick Emulator QEMU 2.11.0 and older was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto th...
