A server could send a SSHMSGCHANNELREQUEST packet with an exit signal message with a length of max unsigned integer value. The length would then have a value of 1 added to it and used to allocate memory causing a possible memory write out of bounds error or zero byte allocation.

A server could send a value approching unsinged int max number of keyboard prompt requests which could result in an unchecked interger overflow. The value would then be used to allocate memory causing a possible memory write out of bounds error.

Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71.

A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification.

In PuTTY versions before 0.71 on Windows, local attackers could hijack the application by putting a malicious help file in the same directory as the executable.

A vulnerability was found in SQLAlchemy 1.2.17. An SQL Injection when the groupby parameter can be controlled.

ImageMagick is vulnerable to a denial of service, caused by a memory leak in WriteDIBImage in coders/dib.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.

ImageMagick is vulnerable to a denial of service, caused by memory leaks in WritePDFImage in coders/pdf.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.

In ImageMagick before 7.0.8-25, a memory leak exists in WritePSDChannel in coders/psd.c.

In ImageMagick before 7.0.8-25, a memory leak exists in ReadSIXELImage in coders/sixel.c.

ImageMagick could allow a remote attacker to obtain sensitive information, caused by memory leaks in DecodeImage in coders/pcd.c. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to obtain sensitive information.

embed/ephy-web-view.c in GNOME Web (aka Epiphany) through 3.31.4 allows address bar spoofing because a page load triggered by JavaScript leads to updating an address as if it were triggered by a safer visit type (e.g., VISITLINK, VISITTYPED, VISITBOOKMARK, or VISITHOMEPAGE).

Denial of Service Vulnerability in Action View

Impact ------ Specially crafted accept headers can cause the Action View template location code to consume 100% CPU, causing the server unable to process requests. This impacts all Rails applications that render views.

All users running an affected release should either upgrade or use one of the workarounds immediately.

Releases -------- The 6.0.0.beta3, 5.2.2.1, 5.1.6.2, 5.0.7.2, and 4.2.11.1 releases are available at the normal locations.

Workarounds ----------- This vulnerability can be mitigated by wrapping render calls with respondto blocks. For example, the following example is vulnerable:

ruby class UserController < ApplicationController def index render "index" end end

But the following code is not vulnerable:

ruby class UserController < ApplicationController def index respondto |format| format.html { render "index" } end end end

Implicit rendering is impacted, so this code is vulnerable:

ruby class UserController < ApplicationController def index end end

But can be changed this this:

ruby class UserController < ApplicationController def index respondto |format| format.html { render "index" } end end end

Alternatively to specifying the format, the following monkey patch can be applied in an initializer:

$ cat config/initializers/formatsfilter.rb frozenstringliteral: true

ActionDispatch::Request.prepend(Module.new do def formats super().select do |format| format.symbol || format.ref == "/" end end end)

Please note that only the 5.2.x, 5.1.x, 5.0.x, and 4.2.x series are supported at present. Users of earlier unsupported releases are advised to upgrade as soon as possible as we cannot guarantee the continued availability of security fixes for unsupported releases.

Also note that the patches for this vulnerability are the same as CVE-2019-5418.

It was found that the forceput operator could be extracted from the DefineResource method in ghostscript before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER.

It was found that the superexec operator was available in the internal dictionary in ghostscript before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER.

Openwsman, versions up to and including 2.6.9, are vulnerable to infinite loop in processconnection() when parsing specially crafted HTTP requests. A remote, unauthenticated attacker can exploit this vulnerability by sending malicious HTTP request to cause denial of service to openwsman server.

It was found that openwsman can access various secret files without having the correct privileges set. A local attacker could use this for information disclosure.

A vulnerability in the Portable Document Format (PDF) scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of proper data handling mechanisms within the device buffer while indexing remaining file data on an affected device. An attacker could exploit this vulnerability by sending crafted PDF files to an affected device. A successful exploit could allow the attacker to cause a heap buffer out-of-bounds read condition, resulting in a crash that could result in a denial of service condition on an affected device.

A vulnerability in the Object Linking & Embedding (OLE2) file scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms for OLE2 files sent an affected device. An attacker could exploit this vulnerability by sending malformed OLE2 files to the device running an affected version ClamAV Software. An exploit could allow the attacker to cause an out-of-bounds write condition, resulting in a crash that could result in a denial of service condition on an affected device.
