Message #5 received at submit@bugs.debian.org (full text, mbox, reply):
Source: python-rsa

Severity: important
Tags: security upstream
Forwarded: https://github.com/sybrenstuvel/python-rsa/issues/146
Control: found -1 4.0-2
Hi,
The following vulnerability was published for python-rsa.
CVE-2020-13757[0]:
| Python-RSA 4.0 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).
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

[1] https://github.com/sybrenstuvel/python-rsa/issues/146

Regards,
Salvatore
