salt: salt-master process ClearFuncs class does not properly validate method calls

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.

salt: salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users.

salt: sending crafted web requests to the Salt API, with the SSH client enabled, can result in shell injection

An issue was discovered in SaltStack Salt through 3002. Sending crafted web requests to the Salt API, with the SSH client enabled, can result in shell injection.

squid: Mishandled HTML in the host parameter to cachemgr.cgi results in insecure behaviour

Squid before 4.9, when certain web browsers are used, mishandles HTML in the host (aka hostname) parameter to cachemgr.cgi.

rcube_image.php in Roundcube Webmail before 1.4.4 allows attackers to execute arbitrary code via shell metacharacters in a configuration setting for im_convert_path or im_identify_path.

rubygem-actionpack: render file directory traversal in Action View

There is a File Content Disclosure vulnerability in Action View <5.2.2.1, <5.1.6.2, <5.0.7.2, <4.2.11.1 and v3 where specially crafted accept headers can cause contents of arbitrary files on the target system's filesystem to be exposed.

httpd: privilege escalation from modules scripts

In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected.

freetype: Heap-based buffer overflow due to integer truncation in Load_SBit_Png

Heap buffer overflow in Freetype in Google Chrome prior to 86.0.4240.111 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

chromium-browser: Inappropriate implementation in V8

Inappropriate implementation in V8 in Google Chrome prior to 86.0.4240.183 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

chromium-browser: use-after-free in audio

Use after free in WebAudio in Google Chrome prior to 78.0.3904.87 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

xorg-x11-server: information leak in the XkbSetGeometry request of X servers

X.Org Server (aka xserver and xorg-server) before 1.16.3 and 1.17.x before 1.17.1 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (crash) via a crafted string length value in a XkbSetGeometry request.

xorg-x11-server: Xwayland allows unconditional open access to display

The authentication setup in XWayland 1.16.x and 1.17.x before 1.17.2 starts the server in non-authenticating mode, which allows local users to read from or send information to arbitrary X11 clients via vectors involving a UNIX socket.

ImageMagick: division by zero in RemoveDuplicateLayers in MagickCore/layer.c

ImageMagick 7.0.1-0 to 7.0.8-54 Q16 allows Division by Zero in RemoveDuplicateLayers in MagickCore/layer.c.

systemd: memory leak in button_open() in login/logind-button.c when udev events are received

An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur.

systemd: Mishandled symlinks in systemd-tmpfiles allows local users to obtain ownership of arbitrary files

systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.

libpng: buffer overflow in png_inflate caused by invalid type conversions

Integer signedness error in the png_inflate function in pngrutil.c in libpng before 1.4.10beta01, as used in Google Chrome before 17.0.963.83 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file, a different vulnerability than CVE-2011-3026.

Denial of service in nghttp2

In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection.

cpio, as used in build 2007.05.10, 2010.07.28, and possibly other versions, allows remote attackers to overwrite arbitrary files via a symlink within an RPM package archive.

OpenJDK: Missing maximum length check in WindowsNativeDispatcher.asNativeBuffer() (Libraries, 8242695)

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 7u271, 8u261, 11.0.8 and 15; Java SE Embedded: 8u261. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.1 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N).

OpenJDK: Missing permission check in path to URI conversion (Libraries, 8242680)

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 7u271, 8u261, 11.0.8 and 15; Java SE Embedded: 8u261. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security.
