>> Python Multiple Module Buffer and Integer Overflow Vulnerabilities
|
Multiple vulnerabilities have been identified in Python, which could be exploited by attackers to cause a denial of service or compromise a vulnerable system. These issues are caused by integer and buffer overflow errors in various modules including "stringobject", "unicodeobject", "bufferobject", "longobject", "tupleobject", "stropmodule", "gcmodule", "mmapmodule" and "hashlib", and in the "unicode_resize()" and "PyOS_vsnprintf()" functions when processing malformed data, which could be exploited to bypass security restrictions, crash an affected application or execute arbitrary code.
