Memory leaks in code encrypting and verifying RSA payloads

Using crafted public RSA keys which are not compliant with SP 800-56B can cause a small memory leak when encrypting and verifying payloads. An attacker can leverage this flaw to gradually erode available memory to the point where the host crashes for lack of resources. Upon restart the attacker...

Timing Attack

Cryptography is vulnerable to a Timing Attack. This vulnerability is due to the predictable structure of padding in ciphertexts during RSA encryption. This flaw enables an attacker to distinguish between different types of padding errors, potentially leading to the decryption of captured messages...

New ZLoader Malware Variant Surfaces with 64-bit Windows Compatibility

Threat hunters have identified a new campaign that delivers the ZLoader malware, resurfacing nearly two years after the botnet's infrastructure was dismantled in April 2022. A new variant of the malware is said to have been in development since September 2023, Zscaler ThreatLabz said in an analys...

The vulnerability of the transport-layer cryptographic library GnuTLS, related to differences in response times when processing RSA encryption text in the ClientKeyExchange message, with both correct and incorrect PKCS#1 additional fields, allows attackers to gain unauthorized access to protected information.

The vulnerability of the transport-layer cryptographic library GnuTLS is related to differences in response times when processing RSA encryption text in the ClientKeyExchange message, with both correct and incorrect PKCS1 additional fields. Exploiting this vulnerability could allow a remote...

Information Leak

pycryptodome and pycryptodomex are vulnerable to Information Leakage. The vulnerability is caused due to a side-channel leakage for OAEP decryption Optimal Asymmetric Encryption Padding used during RSA encryption.
