The signal handler implementations in socat before 1.7.3.0 and 2.0.0-b8 allow remote attackers to cause a denial of service process freeze or crash...

SUSE CVE-2017-7745

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the SIGCOMP dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-sigcomp.c by correcting a memory-size check...

SUSE CVE-2017-15537

The x86/fpu Floating Point Unit subsystem in the Linux kernel before 4.13.5, when a processor supports the xsave feature but not the xsaves feature, does not correctly handle attempts to set reserved bits in the xstate header via the ptrace or rtsigreturn system call, allowing local users to read...

SUSE CVE-2017-1000255

On Linux running on PowerPC hardware Power8 or later a user process can craft a signal frame and then do a sigreturn so that the kernel will take an exception interrupt, and use the r1 value from the signal frame as the kernel stack pointer. As part of the exception entry the content of the signa...

SUSE CVE-2020-1751

An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the frame address, resulting in a denial of service or potential code execution. The highest...

SUSE CVE-2020-12826

A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because execid in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a donotifyparent protection mechanism. A child process can send an arbitrary signal to a parent...

SUSE CVE-2020-15669

When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to be notified. This results in a use-after-free and we presume that with enough effort it could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR 68.12 and...

SUSE CVE-2020-35508

A flaw possibility of race condition and incorrect initialization of the process id was found in the Linux kernel child/parent process identification handling while filtering signal handlers. A local attacker is able to abuse this flaw to bypass checks to send any signal to a privileged process...

SUSE CVE-2021-20265

A flaw was found in the way memory resources were freed in the unixstreamrecvmsg function in the Linux kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by exhausting available memory. The highest threat from this vulnerability is to system...

SUSE CVE-2021-28951

An issue was discovered in fs/iouring.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service deadlock because exit may be waiting to park a SQPOLL thread, but concurrently that SQPOLL thread is waiting for a signal to start, aka CID-3ebba796fa25...

Name of the Vulnerable Software and Affected Versions: Linux Kernel versions prior to v5.15.92 Description: The issue is related to the bpf in the Linux Kernel, specifically with skipping tasks with pid=1 in send signal common. The actual impact and attack plausibility have not yet been proven...

PT-2023-19717

Name of the Vulnerable Software and Affected Versions GNU Screen versions through 4.9.0 Description The issue allows local users to send a privileged SIGHUP signal to any PID, causing a denial of service or disruption of the target process. This occurs when GNU Screen is installed setuid or setgi...

XDR, the Beatles, and Blunt Instruments

Sometimes tools are blunt because there’s nothing else. Regarding economic controls for example, Fed Chair Jerome Powell said: “We have essentially interest rates, the balance sheet and forward guidance. They are famously blunt tools, they are not capable of surgical precision." Others are blunt...
