CVE-2024-0553 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gnutls, Enterprise Linux 2026-06-17 N/A 7.5 HIGH
A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.
CVE-2024-0436 1 Mintplexlabs 1 Anythingllm 2026-06-17 N/A 5.9 MEDIUM
Theoretically, it would be possible for an attacker to brute-force the password for an instance in single-user password protection mode via a timing attack given the linear nature of the `!==` used for comparison. The risk is minified by the additional overhead of the request, which varies in a non-constant nature making the attack less reliable to execute
CVE-2024-0202 1 Cryptlib 1 Cryptlib 2026-06-17 N/A 5.9 MEDIUM
A security vulnerability has been identified in the cryptlib cryptographic library when cryptlib is compiled with the support for RSA key exchange ciphersuites in TLS (by setting the USE_RSA_SUITES define), it will be vulnerable to the timing variant of the Bleichenbacher attack. An attacker that is able to perform a large number of connections to the server will be able to decrypt RSA ciphertexts or forge signatures using server's certificate. THIS CVE ID IS CURRENTLY DISPUTED - MAINTAINER NOTE: There are only two situations where it's enabled, one is for fuzz-testing to exercise code paths that wouldn't otherwise be available, the other is for static source code analysis with tools like Coverity and Prefast, again to open up code paths that otherwise wouldn't be available. It can also be enabled manually in two specific test builds just to make sure the code still compiles OK, to avoid bit rot and verify that the fuzz-testing build will compile without errors.
CVE-2023-6935 1 Wolfssl 1 Wolfssl 2026-06-17 N/A 5.9 MEDIUM
wolfSSL SP Math All RSA implementation is vulnerable to the Marvin Attack, new variation of a timing Bleichenbacher style attack, when built with the following options to configure: --enable-all CFLAGS="-DWOLFSSL_STATIC_RSA" The define “WOLFSSL_STATIC_RSA” enables static RSA cipher suites, which is not recommended, and has been disabled by default since wolfSSL 3.6.6.  Therefore the default build since 3.6.6, even with "--enable-all", is not vulnerable to the Marvin Attack. The vulnerability is specific to static RSA cipher suites, and expected to be padding-independent. The vulnerability allows an attacker to decrypt ciphertexts and forge signatures after probing with a large number of test observations. However the server’s private key is not exposed.
CVE-2023-6258 1 Latchset 1 Pkcs11-provider 2026-06-17 N/A 8.1 HIGH
A security vulnerability has been identified in the pkcs11-provider, which is associated with Public-Key Cryptography Standards (PKCS#11). If exploited successfully, this vulnerability could result in a Bleichenbacher-like security flaw, potentially enabling a side-channel attack on PKCS#1 1.5 decryption.
CVE-2023-6240 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-17 N/A 6.5 MEDIUM
A Marvin vulnerability side-channel leakage was found in the RSA decryption operation in the Linux Kernel. This issue may allow a network attacker to decrypt ciphertexts or forge signatures, limiting the services that use that private key.
CVE-2023-6135 1 Mozilla 1 Firefox 2026-06-17 N/A 4.3 MEDIUM
Multiple NSS NIST curves were susceptible to a side-channel attack known as "Minerva". This attack could potentially allow an attacker to recover the private key. This vulnerability affects Firefox < 121.
CVE-2023-5992 2 Opensc Project, Redhat 11 Opensc, Enterprise Linux, Enterprise Linux Eus and 8 more 2026-06-17 N/A 5.6 MEDIUM
A vulnerability was found in OpenSC where PKCS#1 encryption padding removal is not implemented as side-channel resistant. This issue may result in the potential leak of private data.
CVE-2023-5981 4 Debian, Fedoraproject, Gnu and 1 more 4 Debian Linux, Fedora, Gnutls and 1 more 2026-06-17 N/A 5.9 MEDIUM
A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.
CVE-2023-5872 2026-06-17 N/A 4.3 MEDIUM
In Wago Smart Designer in versions up to 2.33.1 a low privileged remote attacker may enumerate projects and usernames through iterative requests to an specific endpoint.
CVE-2023-5722 1 Mozilla 1 Firefox 2026-06-17 N/A 5.3 MEDIUM
Using iterative requests an attacker was able to learn the size of an opaque response, as well as the contents of a server-supplied Vary header. This vulnerability affects Firefox < 119.
CVE-2023-5410 2026-06-17 N/A 8.2 HIGH
A potential security vulnerability has been reported in the system BIOS of certain HP PC products, which might allow memory tampering. HP is releasing mitigation for the potential vulnerability.
CVE-2023-5388 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 6.5 MEDIUM
NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could potentially allow an attacker to recover the private data. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
CVE-2023-53943 1 Glpi-project 1 Glpi 2026-06-17 N/A 5.3 MEDIUM
GLPI 9.5.7 contains a username enumeration vulnerability in the lost password recovery mechanism that allows attackers to validate email addresses. Attackers can systematically test email addresses by submitting requests to the password reset endpoint and analyzing response differences to identify valid user accounts.
CVE-2023-52323 1 Pycryptodome 2 Pycryptodome, Pycryptodomex 2026-06-17 N/A 5.9 MEDIUM
PyCryptodome and pycryptodomex before 3.19.1 allow side-channel leakage for OAEP decryption, exploitable for a Manger attack.
CVE-2023-51437 1 Apache 1 Pulsar 2026-06-17 N/A 7.4 HIGH
Observable timing discrepancy vulnerability in Apache Pulsar SASL Authentication Provider can allow an attacker to forge a SASL Role Token that will pass signature verification. Users are recommended to upgrade to version 2.11.3, 3.0.2, or 3.1.1 which fixes the issue. Users should also consider updating the configured secret in the `saslJaasServerRoleTokenSignerSecretPath` file. Any component matching an above version running the SASL Authentication Provider is affected. That includes the Pulsar Broker, Proxy, Websocket Proxy, or Function Worker. 2.11 Pulsar users should upgrade to at least 2.11.3. 3.0 Pulsar users should upgrade to at least 3.0.2. 3.1 Pulsar users should upgrade to at least 3.1.1. Any users running Pulsar 2.8, 2.9, 2.10, and earlier should upgrade to one of the above patched versions.

CVE-2023-50782 3 Couchbase, Cryptography.io, Redhat 5 Couchbase Server, Cryptography, Ansible Automation Platform and 2 more 2026-06-17 N/A 7.5 HIGH
A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.
CVE-2023-50708 1 Yiiframework 1 Yii2-authclient 2026-06-17 N/A 6.1 MEDIUM
yii2-authclient is an extension that adds OpenID, OAuth, OAuth2 and OpenId Connect consumers for the Yii framework 2.0. In yii2-authclient prior to version 2.2.15, the Oauth1/2 `state` and OpenID Connect `nonce` is vulnerable for a `timing attack` since it is compared via regular string comparison (instead of `Yii::$app->getSecurity()->compareString()`). Version 2.2.15 contains a patch for the issue. No known workarounds are available.
