CVE-2018-18203 1 Subaru 6 Starlink 2017, Starlink 2017 Firmware, Starlink 2018 and 3 more 2019-02-05 6.9 MEDIUM 6.4 MEDIUM
A vulnerability in the update mechanism of Subaru StarLink Harman head units 2017, 2018, and 2019 may give an attacker (with physical access to the vehicle's USB ports) the ability to rewrite the firmware of the head unit. This occurs because the device accepts modified QNX6 filesystem images (as long as the attacker obtains access to certain Harman decryption/encryption code) as a consequence of a bug where unsigned images pass a validity check. An attacker could potentially install persistent malicious head unit firmware and execute arbitrary code as the root user.
CVE-2018-16149 1 Axtls Project 1 Axtls 2019-01-31 4.3 MEDIUM 5.9 MEDIUM
In sig_verify() in x509.c in axTLS version 2.1.3 and before, the PKCS#1 v1.5 signature verification blindly trusts the declared lengths in the ASN.1 structure. Consequently, when small public exponents are being used, a remote attacker can generate purposefully crafted signatures (and put them on X.509 certificates) to induce illegal memory access and crash the verifier.
CVE-2018-8955 1 Bitdefender 1 Gravityzone 2019-01-25 7.5 HIGH 9.8 CRITICAL
The installer for BitDefender GravityZone relies on an encoded string in a filename to determine the URL for installation metadata, which allows remote attackers to execute arbitrary code by changing the filename while leaving the file's digital signature unchanged.
CVE-2018-15836 1 Xelerance 1 Openswan 2019-01-10 5.0 MEDIUM 7.5 HIGH
In verify_signed_hash() in lib/liboswkeys/signatures.c in Openswan before 2.6.50.1, the RSA implementation does not verify the value of padding string during PKCS#1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used. IKEv2 signature verification is affected when RAW RSA keys are used.
CVE-2018-16150 1 Axtls Project 1 Axtls 2018-12-13 4.3 MEDIUM 5.9 MEDIUM
In sig_verify() in x509.c in axTLS version 2.1.3 and before, the PKCS#1 v1.5 signature verification does not reject excess data after the hash value. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation through fake X.509 certificates. This is a variant of CVE-2006-4340.
CVE-2018-16253 1 Axtls Project 1 Axtls 2018-12-13 4.3 MEDIUM 5.9 MEDIUM
In sig_verify() in x509.c in axTLS version 2.1.3 and before, the PKCS#1 v1.5 signature verification does not properly verify the ASN.1 metadata. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation through fake X.509 certificates. This is an even more permissive variant of CVE-2006-4790 and CVE-2014-1568.
CVE-2018-1000539 1 Json-jwt Project 1 Json-jwt 2018-09-02 5.0 MEDIUM 5.3 MEDIUM
Nov json-jwt version >= 0.5.0 && < 1.9.4 contains a CWE-347: Improper Verification of Cryptographic Signature vulnerability in Decryption of AES-GCM encrypted JSON Web Tokens that can result in Attacker can forge a authentication tag. This attack appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in 1.9.4 and later.
CVE-2018-10407 1 Carbonblack 1 Carbon Black Cb 2018-08-10 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in Carbon Black Cb Response. A maliciously crafted Universal/fat binary can evade third-party code signing checks. By not completing full inspection of the Universal/fat binary, the user of the third-party tool will believe that the code is signed by Apple, but the malicious unsigned code will execute.
CVE-2018-3756 1 Hyperledger 1 Iroha 2018-07-18 5.0 MEDIUM 7.5 HIGH
Hyperledger Iroha versions v1.0_beta and v1.0.0_beta-1 are vulnerable to transaction and block signature verification bypass in the transaction and block validator allowing a single node to sign a transaction and/or block multiple times, each with a random nonce, and have other validating nodes accept them as separate valid signatures.
CVE-2017-18146 1 Qualcomm 56 Mdm9206, Mdm9206 Firmware, Mdm9607 and 53 more 2018-05-14 10.0 HIGH 9.8 CRITICAL
In Android before security patch level 2018-04-05 on Qualcomm Snapdragon Automobile, Snapdragon Mobile, and Snapdragon Wear MDM9206, MDM9607, MDM9650, MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 425, SD 430, SD 450, SD 615/16/SD 415, SD 617, SD 625, SD 650/52, SD 800, SD 808, SD 810, SD 820, SD 820A, SD 835, SD 845, SD 850, in some corner cases, ECDSA signature verification can fail.
CVE-2018-7711 2 Debian, Simplesamlphp 3 Debian Linux, Saml2, Simplesamlphp 2018-03-29 6.8 MEDIUM 8.1 HIGH
HTTPRedirect.php in the saml2 library in SimpleSAMLphp before 1.15.4 has an incorrect check of return values in the signature validation utilities, allowing an attacker to get invalid signatures accepted as valid by forcing an error during validation. This occurs because of a dependency on PHP functionality that interprets a -1 error code as a true boolean value.
CVE-2018-0489 3 Arubanetworks, Debian, Shibboleth 3 Clearpass, Debian Linux, Xmltooling-c 2018-03-23 6.4 MEDIUM 6.5 MEDIUM
Shibboleth XMLTooling-C before 1.6.4, as used in Shibboleth Service Provider before 2.6.1.4 on Windows and other products, mishandles digital signatures of user data, which allows remote attackers to obtain sensitive information or conduct impersonation attacks via crafted XML data. NOTE: this issue exists because of an incomplete fix for CVE-2018-0486.
CVE-2018-0486 2 Debian, Shibboleth 2 Debian Linux, Xmltooling-c 2018-02-15 6.4 MEDIUM 6.5 MEDIUM
Shibboleth XMLTooling-C before 1.6.3, as used in Shibboleth Service Provider before 2.6.0 on Windows and other products, mishandles digital signatures of user attribute data, which allows remote attackers to obtain sensitive information or conduct impersonation attacks via a crafted DTD.
