USN-3407-1 pyjwt vulnerability

It was discovered that a vulnerability in PyJWT doesn't check invalidstrings properly for some public keys. A remote attacker could take advantage of a key confusion to craft JWTs from scratch...

PYSEC-2017-24

In PyJWT 1.5.0 and below the invalidstrings check in HMACAlgorithm.preparekey does not account for all PEM encoded public keys. Specifically, the PKCS1 PEM encoded format would be allowed because it is prefaced with the string -----BEGIN RSA PUBLIC KEY----- which is not accounted for. This enable...

Key Confusion Attacks

PyJWT is vulnerable to asymmetric/symmetric key confusion attacks. PKCS1 PEM keys that begin with -----BEGIN RSA PUBLIC KEY----- will not be rejected by the invalidstrings check in HMACAlgorithm.preparekey. Using this flaw, attackers can cause symmetric/asymmetric confusion and create JWTs from...

Code injection

Unspecified vulnerability in NewzCrawler 1.8 allows remote attackers to cause a denial of service application instability via certain invalid strings in the URL attribute of an ENCLOSURE element, as demonstrated by a "%s" sequence, a "%Y" sequence, a "%%" sequence, and an "n," sequence...
