Vulnerabilities > Improper Verification of Cryptographic Signature
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2018-11-07 | CVE-2018-16150 | Improper Verification of Cryptographic Signature vulnerability in Axtls Project Axtls 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. | 5.9 |
| 2018-11-07 | CVE-2018-16149 | Improper Verification of Cryptographic Signature vulnerability in Axtls Project Axtls 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. | 5.9 |
| 2018-10-26 | CVE-2018-18653 | Improper Verification of Cryptographic Signature vulnerability in Canonical Ubuntu Linux 18.10 The Linux kernel, as used in Ubuntu 18.10 and when booted with UEFI Secure Boot enabled, allows privileged local users to bypass intended Secure Boot restrictions and execute untrusted code by loading arbitrary kernel modules. | 7.8 |
| 2018-10-24 | CVE-2018-8955 | Improper Verification of Cryptographic Signature vulnerability in Bitdefender Gravityzone 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. | 9.8 |
| 2018-10-05 | CVE-2018-15374 | Improper Verification of Cryptographic Signature vulnerability in Cisco IOS XE 16.6.1 A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install a malicious software image or file on an affected device. | 6.7 |
| 2018-09-26 | CVE-2018-16152 | Improper Verification of Cryptographic Signature vulnerability in multiple products In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data in the digestAlgorithm.parameters field during PKCS#1 v1.5 signature verification. | 7.5 |
| 2018-09-26 | CVE-2018-16151 | Improper Verification of Cryptographic Signature vulnerability in multiple products In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data after the encoded algorithm OID during PKCS#1 v1.5 signature verification. | 7.5 |
| 2018-09-26 | CVE-2018-15836 | Improper Verification of Cryptographic Signature vulnerability in Xelerance Openswan 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. | 7.5 |
| 2018-09-18 | CVE-2018-16515 | Improper Verification of Cryptographic Signature vulnerability in multiple products Matrix Synapse before 0.33.3.1 allows remote attackers to spoof events and possibly have unspecified other impacts by leveraging improper transaction and event signature validation. | 8.8 |
| 2018-08-31 | CVE-2018-7685 | Improper Verification of Cryptographic Signature vulnerability in Opensuse Libzypp The decoupled download and installation steps in libzypp before 17.5.0 could lead to a corrupted RPM being left in the cache, where a later call would not display the corrupted RPM warning and allow installation, a problem caused by malicious warnings only displayed during download. | 7.8 |
