An issue was discovered in the libp2p-core crate before 0.8.1 for Rust. Attackers can spoof ed25519 signatures.

rubygem-rest-client: code-execution backdoor insterted by third party

The rest-client gem 1.6.10 through 1.6.13 for Ruby, as distributed on RubyGems.org, included a code-execution backdoor inserted by a third party. Versions <=1.6.9 and >=1.6.14 are unaffected.

libpcap: Information disclosure in rpcapd/daemon.c

rpcapd/daemon.c in libpcap before 1.9.1 on non-Windows platforms provides details about why authentication failed, which might make it easier for attackers to enumerate valid usernames.

A security vulnerability exists in the Zingbox Inspector versions 1.293 and earlier, that could allow an attacker to supply an invalid software update image to the Zingbox Inspector that could result in command injection.

python-ecdsa: DER encoding is not being verified in signatures

A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.

chromium-browser: Incorrect security UI in sharing

Incorrect security UI in sharing in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to perform domain spoofing via a crafted HTML page.

chromium-browser: CSRF bypass

Insufficient policy enforcement in Blink in Google Chrome prior to 77.0.3865.75 allowed a remote attacker to bypass content security policy via a crafted HTML page.

Auth0 Passport-SharePoint before 0.4.0 does not validate the JWT signature of an Access Token before processing. This allows attackers to forge tokens and bypass authentication and authorization mechanisms.

verification.py in django-rest-registration (aka Django REST Registration library) before 0.5.0 relies on a static string for signatures (i.e., the Django Signing API is misused), which allows remote attackers to spoof the verification process. This occurs because incorrect code refactoring led to calling a security-critical function with an incorrect argument.

Hunesion i-oneNet Missing Support for Integrity Check vulnerability

In Hunesion i-oneNet version 3.0.7 ~ 3.0.53 and 4.0.4 ~ 4.0.16, due to the lack of update file integrity checking in the upgrade process, an attacker can craft malicious file and use it as an update.

Cisco NX-OS and IOS XE Software Virtual Service Image Signature Bypass Vulnerability

A vulnerability in Cisco NX-OS Software and Cisco IOS XE Software could allow an authenticated, local attacker with valid administrator or privilege level 15 credentials to load a virtual service image and bypass signature verification on an affected device. The vulnerability is due to improper signature verification during the installation of an Open Virtual Appliance (OVA) image. An authenticated, local attacker could exploit this vulnerability and load a malicious, unsigned OVA image on an affected device. A successful exploit could allow an attacker to perform code execution on a crafted software OVA image.

Cisco IOS XE Software Digital Signature Verification Bypass Vulnerability

A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability exists because, under certain circumstances, an affected device can be configured to not verify the digital signatures of system image files during the boot process. An attacker could exploit this vulnerability by abusing a specific feature that is part of the device boot process. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device.

Cisco HyperFlex Software Counter Value Injection Vulnerability

A vulnerability in the statistics collection service of Cisco HyperFlex Software could allow an unauthenticated, remote attacker to inject arbitrary values on an affected device. The vulnerability is due to insufficient authentication for the statistics collection service. An attacker could exploit this vulnerability by sending properly formatted data values to the statistics collection service of an affected device. A successful exploit could allow the attacker to cause the web interface statistics view to present invalid data to users.

Auth Bypass Via X-Forwarded-For Header in SOAP API

In NETGEAR Nighthawk X10-R900 prior to 1.0.4.26, an attacker may bypass all authentication checks on the device's "NETGEAR Genie" SOAP API ("/soap/server_sa") by supplying a malicious X-Forwarded-For header of the device's LAN IP address (192.168.1.1) in every request. As a result, an attacker may modify almost all of the device's settings and view various configuration settings.

Enigmail before 2.0.11 allows PGP signature spoofing: for an inline PGP message, an attacker can cause the product to display a "correctly signed" message indication, but display different unauthenticated text.

A message-forgery issue was discovered in crypto/openpgp/clearsign/clearsign.go in supplementary Go cryptography libraries 2019-03-25. According to the OpenPGP Message Format specification in RFC 4880 chapter 7, a cleartext signed message can contain one or more optional "Hash" Armor Headers. The "Hash" Armor Header specifies the message digest algorithm(s) used for the signature. However, the Go clearsign package ignores the value of this header, which allows an attacker to spoof it. Consequently, an attacker can lead a victim to believe the signature was generated using a different message digest algorithm than what was actually used. Moreover, since the library skips Armor Header parsing in general, an attacker can not only embed arbitrary Armor Headers, but also prepend arbitrary text to cleartext messages without invalidating the signatures.

org.eclipse.paho.client.mqttv3: Improper hostname validation in the MQTT library

In the Eclipse Paho Java client library version 1.2.0, when connecting to an MQTT server using TLS and setting a host name verifier, the result of that verification is not checked. This could allow one MQTT server to impersonate another and provide the client library with incorrect information.

Mozilla: document.domain-based origin isolation has same-origin-property violation

If two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.

thunderbird: spoofing a message author via a crafted S/MIME

A crafted S/MIME message consisting of an inner encryption layer and an outer SignedData layer was shown as having a valid digital signature, although the signer might have had no access to the contents of the encrypted message, and might have stripped a different signature from the encrypted message. Previous versions had only suppressed showing a digital signature for messages with an outer multipart/signed layer. This vulnerability affects Thunderbird < 68.1.1.

Mozilla: Content security policy directives ignore port and path if host is a wildcard

If a wildcard ('*') is specified for the host in Content Security Policy (CSP) directives, any port or path restriction of the directive will be ignored, leading to CSP directives not being properly applied to content. This vulnerability affects Firefox < 69.
