Vulnerabilities (CVE)

In arch/x86/kvm/vmx.c in the Linux kernel before 4.17.2, when nested virtualization is used, local attackers could cause L1 KVM guests to VMEXIT, potentially allowing privilege escalations and denial of service attacks due to lack of checking of CPL.

An issue was discovered in Xen through 4.10.x. One of the fixes in XSA-260 added some safety checks to help prevent Xen livelocking with debug exceptions. Unfortunately, due to an oversight, at least one of these safety checks can be triggered by a guest. A malicious PV guest can crash Xen, leading to a Denial of Service. All Xen systems which have applied the XSA-260 fix are vulnerable. Only x86 systems are vulnerable. ARM systems are not vulnerable. Only x86 PV guests can exploit the vulnerabi ... An issue was discovered in Xen through 4.10.x. One of the fixes in XSA-260 added some safety checks to help prevent Xen livelocking with debug exceptions. Unfortunately, due to an oversight, at least one of these safety checks can be triggered by a guest. A malicious PV guest can crash Xen, leading to a Denial of Service. All Xen systems which have applied the XSA-260 fix are vulnerable. Only x86 systems are vulnerable. ARM systems are not vulnerable. Only x86 PV guests can exploit the vulnerability. x86 HVM and PVH guests cannot exploit the vulnerability. An attacker needs to be able to control hardware debugging facilities to exploit the vulnerability, but such permissions are typically available to unprivileged users.

An issue was discovered in Xen through 4.10.x. Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing the conditions through its own page table contents, a malicious guest may cause such bypasses to be used for an unbounded number of iterations. A malicious or buggy PV guest may cause a Denial of Service (DoS) affecting ... An issue was discovered in Xen through 4.10.x. Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing the conditions through its own page table contents, a malicious guest may cause such bypasses to be used for an unbounded number of iterations. A malicious or buggy PV guest may cause a Denial of Service (DoS) affecting the entire host. Specifically, it may prevent use of a physical CPU for an indeterminate period of time. All Xen versions from 3.4 onwards are vulnerable. Xen versions 3.3 and earlier are vulnerable to an even wider class of attacks, due to them lacking preemption checks altogether in the affected code paths. Only x86 systems are affected. ARM systems are not affected. Only multi-vCPU x86 PV guests can leverage the vulnerability. x86 HVM or PVH guests as well as x86 single-vCPU PV ones cannot leverage the vulnerability.

GIMP through 2.10.2 makes g_get_tmp_dir calls to establish temporary filenames, which may result in a filename that already exists, as demonstrated by the gimp_write_and_read_file function in app/tests/test-xcf.c. This might be leveraged by attackers to overwrite files or read file content that was intended to be private.

demangle_template in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30, allows attackers to trigger excessive memory consumption (aka OOM) during the "Create an array for saving the template argument values" XNEWVEC call. This can occur during execution of objdump.

SV3C L-SERIES HD CAMERA V2.3.4.2103-S50-NTD-B20170508B and V2.3.4.2103-S50-NTD-B20170823B devices allow remote authenticated users to reset arbitrary accounts via a request to web/cgi-bin/hi3510/param.cgi.

When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use an ACL file, and that ACL file is empty, or contains only comments or blank lines, then Mosquitto will treat this as though no ACL file has been defined and use a default allow policy. The new behaviour is to have an empty ACL file mean that all access is denied, which is not a useful configuration but is not unexpected.

In Eclipse Jetty Server, all 9.x versions, on webapps deployed using default Error Handling, when an intentionally bad query arrives that doesn't match a dynamic url-pattern, and is eventually handled by the DefaultServlet's static file serving, the bad characters can trigger a java.nio.file.InvalidPathException which includes the full path to the base resource directory that the DefaultServlet and/or webapp is using.

In Eclipse Jetty Server, all 9.x versions, on webapps deployed using default Error Handling, when an intentionally bad query arrives that doesn't match a dynamic url-pattern, and is eventually handled by the DefaultServlet's static file serving, the bad characters can trigger a java.nio.file.InvalidPathException which includes the full path to the base resource directory that the DefaultServlet and/or webapp is using. If this InvalidPathException is then handled by the default Error Handler, the InvalidPathException message is included in the error response, revealing the full server path to the requesting system.

The web server component of TIBCO Software Inc's Spotfire Statistics Services contains multiple vulnerabilities that may allow the remote execution of code. Without needing to authenticate, an attacker may be able to remotely execute code with the permissions of the system account used to run the web server component. Affected releases are TIBCO Software Inc. TIBCO Spotfire Statistics Services versions up to and including 7.11.0.

A cached side channel attack during handshakes using RSA encryption could allow for the decryption of encrypted content. This is a variant of the Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack) and affects all NSS versions prior to NSS 3.41.

If a site is loaded over a HTTPS connection but loads a favicon resource over HTTP, the mixed content warning is not displayed to users. This vulnerability affects Firefox < 63.

By using the reflected URL in some special resource URIs, such as chrome:, it is possible to inject stylesheets and bypass Content Security Policy (CSP). This vulnerability affects Firefox < 63.

By rewriting the Host: request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63.

Windows 10 does not warn users before opening executable files with the SettingContent-ms extension even when they have been downloaded from the internet and have the "Mark of the Web." Without the warning, unsuspecting users unfamiliar with this new file type might run an unwanted executable. This also allows a WebExtension with the limited downloads.open permission to execute arbitrary code without user interaction on Windows 10 systems. *Note: this issue only affects Windows operating systems ...
