sqlite: an array-bounds overflow if billions of bytes are used in a string argument to a C API

An array-bounds overflow vulnerability was discovered in SQLite. The vulnerability occurs when handling an overly large input passed as a string argument to some of the C-language APIs provided by SQLite. This flaw allows a remote attacker to pass specially crafted large input to the application...

pkgconf security vulnerabilities

pkgconf is a program from pkgconf open source that helps configure compiler and linker flags for development libraries. A security vulnerability exists in pkgconf version 1.9.3 and earlier versions, which stems from variable duplication leading to unbounded string expansion...

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.
