CVE-2021-22212: Use of a Broken or Risky Cryptographic Algorithm

ntpkeygen can generate keys that ntpd fails to parse. NTPsec 1.2.0 allows ntpkeygen to generate keys with '' characters. ntpd then either pads, shortens the key, or fails to load these keys entirely, depending on the key type and the placement of the ''. This results in the administrator not bein...

nettle: Out of bounds memory access in signature verification

A flaw was found in Nettle, where several Nettle signature verification functions GOST DSA, EDDSA & ECDSA result in the Elliptic Curve Cryptography point ECC multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an...

PYSEC-2021-93

An issue was discovered in Pillow before 8.2.0. For EPS data, the readline implementation used in EPSImageFile has to deal with any combination of \r and \n as line endings. It used an accidentally quadratic method of accumulating lines while looking for a line ending. A malicious EPS file could...
