An unprivileged attacker can craft a user-space process with a malicious ELF binary containing an out-of-range shlink field. When root-level dtrace attaches to -- or instruments -- that process (via dtrace -p , pid probes, or USDT), the ELF parser reads heap memory beyond the allocated section cache array without any bounds check. This results in an uninitialized/out-of-bounds heap read that can cause a NULL pointer dereference crash of the dtrace process (DoS), or -- depending on heap layout -- a read-then-use of a garbage pointer controlled by adjacent allocations, providing a foothold toward further exploitation in a privileged context.

An unprivileged attacker can reliably trigger a crash of the dtrace process with a malicious ELF binary due to an integer Divide-by-Zero in Pbuildfilesymtab()

A DTrace component, dtprobed, allows arbitrary file creation through crafted USDT provider names.

A race condidition in systemd-coredump allows a local attacker to crash a SUID program and gain read access to the resulting core dump

In the Unbreakable Enterprise Kernel (UEK), the RDS module in UEK has two setsockopt(2) options, RDSCONNRESET and RDS6CONNRESET, that are not re-entrant. A malicious local user with CAPNETADMIN can use this to crash the kernel. CVSS 3.1 Base Score 5.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

A flaw in netrdsallocsgs() in Oracle Linux kernels allows unprivileged local users to crash the machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

A bug that allows linux kernel lockdown to be trivially bypassed using IMA.

The code in UEK6 U3 was missing an appropiate file descriptor count to be missing. This resulted in a use count error that allowed a file descriptor to a socket to be closed and freed while it was still in use by another portion of the kernel. An attack with local access can operate on the socket, and cause a denial of service. CVSS 3.1 Base Score 5.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

A flaw was found in kernel/debug/debugcore.c in the Linux kernel in the lockdown mode. In this flaw, an attacker with local access could trigger the debugger, bypass lockdown and write anonymously.

In this flaw, KGDB and KDB allow read and write access to kernel memory, and thus should not be allowed during lockdown. An attacker with access to a serial port could trigger the debugger and use it to bypass lockdown.

ntpq in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash) via crafted mode 6 response packets.

The cryptoxmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash). NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750.

ntpd in NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (NULL pointer dereference) via a ntpdc reslist command.

Unspecified vulnerability in the kernel-uek component in Oracle Linux 6 allows local users to affect availability via unknown vectors.

The readCodersInfo function in archivereadsupportformat7zip.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted 7z file, related to the 7zfolder struct.

The certrevoke command in FreeIPA does not check for the "revoke certificate" permission, which allows remote authenticated users to revoke arbitrary certificates by leveraging the "retrieve certificate" permission.

Heap-based buffer overflow in the ClearKey Content Decryption Module (CDM) in the Encrypted Media Extensions (EME) API in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 might allow remote attackers to execute arbitrary code by providing a malformed video and leveraging a Gecko Media Plugin (GMP) sandbox bypass.

It was found that a malicious guest user could submit more requests than the virtqueue size permits, resulting in a crash of the host QEMU process.

The guest could submit requests without bothering to wait for completion and is therefore not bound by virtqueue size. This requires reusing vring descriptors in more than one request, which is incorrect but possible. Processing a request allocates a VirtQueueElement and therefore causes unbounded memory allocation controlled by the guest.

Exit with an error if the guest provides more requests than the virtqueue size permits. This bounds memory allocation and makes the buggy guest visible to the user.

Upstream patch -------------- -> git.qemu.org/?p=qemu.git;a=commit;h=afd9096eb1882f23929f5b5c177898ed231bac66

Integer overflow flaws were found in the way the Hotspot component of OpenJDK read bytecode from class files. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

It was discovered that the CORBA component of OpenJDK did not sufficiently restrict the use of custom ValueHandler when performing object deserialization. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

It was discovered that the JAXP component of OpenJDK did not place a limit on the number of entity replacements performed when parsing XML files. A specially crafted XML document could cause a Java application using JAXP to consume an excessive amount of memory and CPU time when parsed.

Updates correcting this issue address the problem by introducing a limit on the number of entity replacements that can be performed. The limit can be controlled using the jdk.xml.entityReplacementLimit system property.

It was discovered that the JAXP component of OpenJDK did not enforce the maximum XML name limit (jdk.xml.MaxXMLNameLimit) when parsing namespace URIs in XML files. A specially crafted XML document could cause a Java application using JAXP to consume an excessive amount of memory and CPU time when parsed.

It was found that the vfsrename() function did not detect hard links on overlayfs. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to crash the system.

fs/overlayfs/dir.c in the OverlayFS filesystem implementation in the Linux kernel before 4.6 does not properly verify the upper dentry before proceeding with unlink and rename system-call processing, which allows local users to cause a denial of service (system crash) via a rename system call that specifies a self-hardlink.
