CVE-2019-1729 1 Cisco 20 Nexus 3000, Nexus 3100, Nexus 3100-z and 17 more 2024-11-21 6.6 MEDIUM 6.0 MEDIUM
A vulnerability in the CLI implementation of a specific command used for image maintenance for Cisco NX-OS Software could allow an authenticated, local attacker to overwrite any file on the file system including system files. These file overwrites by the attacker are accomplished at the root privilege level. The vulnerability occurs because there is no verification of user-input parameters and or digital-signature verification for image files when using a specific CLI command. An attacker could exploit this vulnerability by authenticating to the device and issuing a command at the CLI. Because an exploit could allow the attacker to overwrite any file on the disk, including system files, a denial of service (DoS) condition could occur. The attacker must have valid administrator credentials for the affected device to exploit this vulnerability.
CVE-2019-1728 1 Cisco 40 Firepower 4110, Firepower 4115, Firepower 4120 and 37 more 2024-11-21 7.2 HIGH 6.7 MEDIUM
A vulnerability in the Secure Configuration Validation functionality of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to run arbitrary commands at system boot time with the privileges of root. The vulnerability is due to a lack of proper validation of system files when the persistent configuration information is read from the file system. An attacker could exploit this vulnerability by authenticating to the device and overwriting the persistent configuration storage with malicious executable files. An exploit could allow the attacker to run arbitrary commands at system startup and those commands will run as the root user. The attacker must have valid administrative credentials for the device.
CVE-2019-1615 1 Cisco 44 9432pq, 9536pq, 9636pq and 41 more 2024-11-21 4.6 MEDIUM 6.7 MEDIUM
A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability is due to improper verification of digital signatures for software images. An attacker could exploit this vulnerability by loading an unsigned software image on an affected device. A successful exploit could allow the attacker to boot a malicious software image. Note: The fix for this vulnerability requires a BIOS upgrade as part of the software upgrade.

CVE-2019-17561 2 Apache, Oracle 2 Netbeans, Graalvm 2024-11-21 5.0 MEDIUM 7.5 HIGH
The "Apache NetBeans" autoupdate system does not fully validate code signatures. An attacker could modify the downloaded nbm and include additional code. "Apache NetBeans" versions up to and including 11.2 are affected by this vulnerability.
CVE-2019-16992 1 Keybase 1 Keybase 2024-11-21 5.0 MEDIUM 7.5 HIGH
The Keybase app 2.13.2 for iOS provides potentially insufficient notice that it is employing a user's private key to sign a certain cryptocurrency attestation (that an address at keybase.io can be used for Stellar payments to the user), which might be incompatible with a user's personal position on the semantics of an attestation.
CVE-2019-16753 2 Decentralized Anonymous Payment System Project, Pivx 2 Decentralized Anonymous Payment System, Private Instant Verified Transactions 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Decentralized Anonymous Payment System (DAPS) through 2019-08-26. The content to be signed is composed of a representation of strings, rather than being composed of their binary representations. This is a weak signature scheme design that would allow the reuse of signatures in some cases (or even the reuse of signatures, intended for one type of message, for another type). This also affects Private Instant Verified Transactions (PIVX) through 3.4.0.
CVE-2019-16732 2 Petwant, Skymee 4 Pf-103, Pf-103 Firmware, Petalk Ai and 1 more 2024-11-21 9.3 HIGH 8.1 HIGH
Unencrypted HTTP communications for firmware upgrades in Petalk AI and PF-103 allow man-in-the-middle attackers to run arbitrary code as the root user.
CVE-2019-15796 3 Canonical, Debian, Ubuntu 3 Ubuntu Linux, Python-apt, Python-apt 2024-11-21 2.6 LOW 4.7 MEDIUM
Python-apt doesn't check if hashes are signed in `Version.fetch_binary()` and `Version.fetch_source()` of apt/package.py or in `_fetch_archives()` of apt/cache.py in version 1.9.3ubuntu2 and earlier. This allows downloads from unsigned repositories which shouldn't be allowed and has been fixed in verisions 1.9.5, 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9.3.5ubuntu3+esm2, and 0.8.3ubuntu7.5.
CVE-2019-15545 1 Libp2p 1 Libp2p 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in the libp2p-core crate before 0.8.1 for Rust. Attackers can spoof ed25519 signatures.
CVE-2019-14859 2 Python-ecdsa Project, Redhat 4 Python-ecdsa, Ceph Storage, Openstack and 1 more 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
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.
CVE-2019-13177 1 Django-rest-registration Project 1 Django-rest-registration 2024-11-21 7.5 HIGH 9.8 CRITICAL
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.
CVE-2019-12662 1 Cisco 135 Ios Xe, Mds 9000, Nexus 3016 and 132 more 2024-11-21 7.2 HIGH 6.7 MEDIUM
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.
CVE-2019-12649 1 Cisco 87 Catalyst 3850-12s-e, Catalyst 3850-12s-s, Catalyst 3850-12xs-e and 84 more 2024-11-21 7.2 HIGH 6.7 MEDIUM
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.
CVE-2019-12269 1 Enigmail 1 Enigmail 2024-11-21 5.0 MEDIUM 7.5 HIGH
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.
CVE-2019-11841 2 Debian, Golang 2 Debian Linux, Crypto 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2019-11755 1 Mozilla 1 Thunderbird 2024-11-21 5.0 MEDIUM 7.5 HIGH
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.
CVE-2019-10575 1 Qualcomm 6 Sda845, Sda845 Firmware, Sdm845 and 3 more 2024-11-21 7.2 HIGH 7.8 HIGH

CVE-2019-10201 1 Redhat 2 Keycloak, Single Sign-on 2024-11-21 5.5 MEDIUM 8.1 HIGH
It was found that Keycloak's SAML broker, versions up to 6.0.1, did not verify missing message signatures. If an attacker modifies the SAML Response and removes the <Signature> sections, the message is still accepted, and the message can be modified. An attacker could use this flaw to impersonate other users and gain access to sensitive information.
