Уязвимость метода pop3lib apop() интерпретатора языка программирования Python, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость метода difflib.IS_LINE_JUNK интерпретатора языка программирования Python, позволяющая нарушителю вызвать отказ в обслуживании

The Wave_read._read_fmt_chunk function in Lib/wave.py in Python through 3.6.4 does not ensure a nonzero channel value, which allows attackers to cause a denial of service (divide-by-zero and exception) via a crafted wav format audio file. NOTE: the vendor disputes this issue because Python applications "need to be prepared to handle a wide variety of exceptions.

python before versions 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic backtracking in pop3lib's apop() method. An attacker could use this flaw to cause denial of service.
