Introduction Introduction Recently we announced a series of blog posts dissecting the exploits released by the ShadowBrokers in April 2017; specifically some of the less explored exploits. This week we are going to take a look at Eternal Synergy, an SMBv1 authenticated exploit. This one is particularly interesting because many of the exploitation steps are purely packet-based, as opposed to local shellcode execution.

CVE-2015-5180 glibc: DNS resolver NULL pointer dereference with crafted record type

The regulator_ena_gpio_free function in drivers/regulator/core.c in the Linux kernel before 3.19 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted application.

The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c.

Use-after-free vulnerability in fs/crypto/ in the Linux kernel before 4.10.7 allows local users to cause a denial of service (NULL pointer dereference) or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be freed prematurely.

When executing a program via the bubblewrap sandbox, the nonpriv session can escape to the parent session by using the TIOCSTI ioctl to push characters into the terminal's input buffer, allowing an attacker to escape the sandbox.

QOS.ch Logback before 1.2.0 has a serialization vulnerability affecting the SocketServer and ServerSocketReceiver components.

Today, a group of eight researchers from across the security industry released a research report on SHA-1 that demonstrates for the first time, a “hash collision” for the full SHA-1 hash algorithm (called “SHAttered”). This is a significant step toward understanding this type of security issue, a milestone in cryptanalysis that has been underway for the past decade.

The windows_icon_typefind function in gst-plugins-base in GStreamer before 1.10.2, when G_SLICE is set to always-malloc, allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted ico file.

KVM in the Linux kernel before 4.8.12, when I/O APIC is enabled, does not properly restrict the VCPU index, which allows guest OS users to gain host OS privileges or cause a denial of service (out-of-bounds array access and host OS crash) via a crafted interrupt request, related to arch/x86/kvm/ioapic.c and arch/x86/kvm/ioapic.h.
