poppler: heap-based buffer over-read in XRef::getEntry in XRef.cc

In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo.

kernel: eBPF: Spectre v1 mitigation bypass

kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks.

Apport contains a TOCTTOU vulnerability when reading the users ~/.apport-ignore.xml

Apport before versions 2.14.1-0ubuntu3.29+esm1, 2.20.1-0ubuntu2.19, 2.20.9-0ubuntu7.7, 2.20.10-0ubuntu27.1, 2.20.11-0ubuntu5 contained a TOCTTOU vulnerability when reading the users ~/.apport-ignore.xml file, which allows a local attacker to replace this file with a symlink to any other file on the system and so cause Apport to include the contents of this other file in the resulting crash report. The crash report could then be read by that user either by causing it to be uploaded and reported to Launchpad, or by leveraging some other vulnerability to read the resulting crash report, and so allow the user to read arbitrary files on the system.

Byobu apport hook uploads user's ~/.screenrc

Byobu Apport hook may disclose sensitive information since it automatically uploads the local user's .screenrc which may contain private hostnames, usernames and passwords. This issue affects: byobu

eXtplorer exposes /usr and /etc/extplorer over HTTP

Information Exposure vulnerability in eXtplorer makes the /usr/ and /etc/extplorer/ system directories world-accessible over HTTP. Introduced in the Makefile patch file debian/patches/debian-changes-2.1.0b6+dfsg-1 or debian/patches/adds-a-makefile.patch, this can lead to data leakage, information disclosure and potentially remote code execution on the web server. This issue affects all versions of eXtplorer in Ubuntu and Debian

Local privilege escalation via snapd socket

Canonical snapd before version 2.37.1 incorrectly performed socket owner validation, allowing an attacker to run arbitrary commands as root. This issue affects: Canonical snapd versions prior to 2.37.1.

Snapd seccomp filter TIOCSTI ioctl bypass

A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl(2) commands on a 64-bit platform; however, the Linux kernel only uses the lower 32 bits to determine which ioctl(2) commands to run. This issue affects: Canonical snapd versions prior to 2.37.4.

Zen Load Balancer 3.10.1 allows remote authenticated admin users to execute arbitrary commands as root via shell metacharacters in the index.cgi?action=View_Cert certname parameter.

Artica Proxy 3.06.200056 allows remote attackers to execute arbitrary commands as root by reading the ressources/settings.inc ldap_admin and ldap_password fields, using these credentials at logon.php, and then entering the commands in the admin.index.php command-line field.

A stored cross-site scripting (XSS) vulnerability in the submit_ticket.php module in the WP Support Plus Responsive Ticket System plugin 9.1.1 for WordPress allows remote attackers to inject arbitrary web script or HTML via the subject parameter in wp-content/plugins/wp-support-plus-responsive-ticket-system/includes/ajax/submit_ticket.php.

An issue was discovered on D-Link DIR-823G devices with firmware through 1.02B03. A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted /HNAP1 request. This occurs when any HNAP API function triggers a call to the system function with untrusted input from the request body, such as a body of ' /bin/telnetd' for the GetDeviceSettingsset API function. Consequently, an attacker can execute any command remotely when they control this input.

An issue was discovered on D-Link DIR-823G devices with firmware through 1.02B03. A command Injection vulnerability allows attackers to execute arbitrary OS commands via shell metacharacters in a crafted /HNAP1 request. This occurs when the GetNetworkTomographyResult function calls the system function with an untrusted input parameter named Address. Consequently, an attacker can execute any command remotely when they control this input.

typora through 0.9.64 has XSS, with resultant remote command execution, during inline rendering of a mathematical formula.

typora through 0.9.63 has XSS, with resultant remote command execution, during block rendering of a mathematical formula.

A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 12.2, macOS Mojave 10.14.4, tvOS 12.2, watchOS 5.2. A local user may be able to read kernel memory.

webkitgtk: arbitrary code execution via malicious web content

A validation issue was addressed with improved logic. This issue is fixed in iOS 12.2, tvOS 12.2, watchOS 5.2, Safari 12.1, iTunes 12.9.4 for Windows, iCloud for Windows 7.11. Processing maliciously crafted web content may result in the disclosure of process memory.

A denial of service issue was addressed with improved memory handling. This issue is fixed in AirPort Base Station Firmware Update 7.8.1, AirPort Base Station Firmware Update 7.9.1. An attacker in a privileged position may be able to perform a denial of service attack.

An access issue was addressed with additional sandbox restrictions. This issue is fixed in Shortcuts 2.1.3 for iOS. A sandboxed process may be able to circumvent sandbox restrictions.

A parsing issue in the handling of directory paths was addressed with improved path validation. This issue is fixed in Shortcuts 2.1.3 for iOS. A local user may be able to view senstive user information.

The issue was addressed with improved validation on the FaceTime server. This issue is fixed in macOS Mojave 10.14.3 Supplemental Update, iOS 12.1.4. A thorough security audit of the FaceTime service uncovered an issue with Live Photos .
