python: CPU denial of service via inefficient IDNA decoder

A vulnerability was discovered in Python. A quadratic algorithm exists when processing inputs to the IDNA RFC 3490 decoder, such that a crafted unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be...

SUSE CVE-2020-10735

A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int"text", a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits float, decimal, int.frombytes, and int for binary bases 2, 4, 8, 16, and 32 are no...

A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases when using int("text") a system could take 50ms to parse an int string with 100000 digits and 5s for 1000000 digits (float decimal int.from_bytes() and int() for binary bases 2 4 8 16 and 32 are not affected). The highest threat from this vulnerability is to system availability.
