okular: local binary execution via specially crafted PDF files

KDE Okular before 1.10.0 allows code execution via an action link in a PDF document.

Privilege escalation in NetHack

NetHack before version 3.6.0 allowed malicious use of escaping of characters in the configuration file (usually .nethackrc) which could be exploited. This bug is patched in NetHack 3.6.0.

Cisco Data Center Network Manager Command Injection Vulnerability

A vulnerability in specific REST API endpoints of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker to inject arbitrary commands on the underlying operating system with the privileges of the logged-in user. The vulnerability is due to insufficient validation of user-supplied input to the API. An attacker could exploit this vulnerability by sending a crafted request to the API. A successful exploit could allow the attacker to inject arbitrary commands on the underlying operating system.

grub2: acpi command allows privileged user to load crafted ACPI tables when Secure Boot is enabled

A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability.

SOFA-Hessian through 4.0.2 allows remote attackers to execute arbitrary commands via a crafted serialized Hessian object because blacklisting of com.caucho.naming.QName and com.sun.org.apache.xpath.internal.objects.XString is mishandled, related to Resin Gadget. NOTE: The vendor doesn’t consider this issue a vulnerability because the blacklist is being misused. SOFA Hessian supports custom blacklist and a disclaimer was posted encouraging users to update the blacklist or to use the whitelist feature for their specific needs since the blacklist is not being actively updated

jenkins-plugin-workflow-remote-loader: Unsafe Script Security whitelist entry in Pipeline Remote Loader Plugin (SECURITY-921)

Jenkins Pipeline Remote Loader Plugin 1.4 and earlier provided a custom whitelist for script security that allowed attackers to invoke arbitrary methods, bypassing typical sandbox protection.

Monstra CMS through 3.0.4 has an incomplete "forbidden types" list that excludes .php (and similar) file extensions but not the .pht or .phar extension, which allows remote authenticated Admins or Editors to execute arbitrary PHP code by uploading a file, a different vulnerability than CVE-2017-18048.

ghostscript: incomplete fix for CVE-2018-16509

It was found that RHSA-2018:2918 did not fully fix CVE-2018-16509. An attacker could possibly exploit another variant of the flaw and bypass the -dSAFER protection to, for example, execute arbitrary shell commands via a specially crafted PostScript document. This only affects ghostscript 9.07 as shipped with Red Hat Enterprise Linux 7.

QEMU: seccomp: blacklist is not applied to all threads

qemu-seccomp.c in QEMU might allow local OS guest users to cause a denial of service (guest crash) by leveraging mishandling of the seccomp policy for threads other than the main thread.

jenkins: Pipeline metadata files not blacklisted in agent-to-master security subsystem (SECURITY-358)

jenkins before versions 2.44, 2.32.2 is vulnerable to an improper blacklisting of the Pipeline metadata files in the agent-to-master security subsystem. This could allow metadata files to be written to by malicious agents (SECURITY-358).

sudo: noexec bypass via wordexp()

sudo before version 1.8.18p1 is vulnerable to a bypass in the sudo noexec restriction if application run via sudo executed wordexp() C library function with a user supplied argument. A local user permitted to run such application via sudo with noexec restriction could possibly use this flaw to execute arbitrary commands with elevated privileges.
