Vulnerability Summary Fixed by
VCID-f4rp-ce4j-xkd3
Aliases:
CVE-2020-13757
GHSA-537h-rv9q-vvph
PYSEC-2020-99
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 causing excessive memory allocation).
4.1
Affected by 1 other vulnerability.
VCID-jeu8-p6h8-8ffx
Aliases:
CVE-2020-25658
GHSA-xrx6-fmxq-rjj2
PYSEC-2020-100
It was found that python-rsa is vulnerable to Bleichenbacher timing attacks. An attacker can use this flaw via the RSA decryption API to decrypt parts of the cipher text encrypted with RSA.
