CVE-2020-12135

https://notcve.org/view.php?id=CVE-2020-12135

bson before 0.8 incorrectly uses int rather than size_t for many variables, parameters, and return values. In particular, the bson_ensure_space() parameter bytesNeeded could have an integer overflow via properly constructed bson input. bson en versiones anteriores a la 0.8 usa incorrectamente int en lugar de size_t para muchas variables, parámetros y valores de retorno. En particular, el parámetro bson_ensure_space () bytesNeeded podría tener un desbordamiento de enteros a través de una entrada bson construida correctamente. • https://bugs.launchpad.net/ubuntu/+source/whoopsie/+bug/1872560 https://github.com/10gen-archive/mongo-c-driver-legacy/commit/1a1f5e26a4309480d88598913f9eebf9e9cba8ca#diff-f7d29a680148f52d6601f59ed787f577 https://launchpadlibrarian.net/474887364/bson-fix-overflow.patch https://usn.ubuntu.com/4450-1 • CWE-190: Integer Overflow or Wraparound •
