Loading vulnerability…
An integer signedness error exists in the zlib extension module of Python 2.5.2 and earlier. The vulnerability allows remote attackers to execute arbitrary code by supplying a negative signed integer, which leads to insufficient memory allocation and a subsequent buffer overflow. The flaw is triggered during the handling of compressed data, where the signedness of an integer is not properly validated, resulting in a miscalculation of buffer size and potential memory corruption.
