Fedora 32 : python27 (2021-17668e344a)

critical Nessus Plugin ID 146412

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 32 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-17668e344a advisory.

 - Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to remote code execution in certain Python applications that accept floating-point numbers as untrusted input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used unsafely. (CVE-2021-3177)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected python27 package.
