cryptacular: excessive memory allocation during a decode operation

CiphertextHeader.java in Cryptacular 1.2.3, as used in Apereo CAS and other products, allows attackers to trigger excessive memory allocation during a decode operation, because the nonce array length associated with "new byte" may depend on untrusted input within the header of encoded data...

Information Disclosure

rsa is vulnerable to information disclosure. The vulnerability exists as rsa ignores prepended \0 bytes during the decryption of a ciphertext in PKCS1v15, where it is supposed to have failed, allowing the interference that this library is used for cryptography...

CVE-2020-13757

Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior such as by...

Memory corruption

Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior such as by...

CVE-2020-13757

CVE-2020-13757 affects the Python-RSA package. Affected: Python-RSA before 4.1. Root cause: decryption ignores leading '\0' bytes in ciphertext. Impact stated in sources: potential DoS risk and information leakage indicators (e.g., attacker could infer usage, or ciphertext length could affect beh...

PT-2020-13658 · Python +5 · Python-Rsa +5

Name of the Vulnerable Software and Affected Versions: Python-RSA versions prior to 4.1 Description: The issue concerns the decryption of ciphertext, where leading '0' bytes are ignored. This could potentially have security implications, such as helping an attacker infer that an application uses...

Bit-Flipping Attack

Amendment This was deemed not a vulnerability. Overview parsel is a gem to encrypt and decrypt data with a given key. Affected versions of this package are vulnerable to Bit-Flipping Attack via the ciphertext function. AES-256-CBC, the construct used in parsel.rb, has no integrity check i.e., the...

Shadowsocks-libev ss-server Stream Cipher Information Disclosure Vulnerability

Summary An exploitable information disclosure vulnerability exists in the network packet handling functionality of Shadowsocks-libev 3.3.2. When utilizing a Stream Cipher, a specially crafted set of network packets can cause an outbound connection from the server, resulting in information...
