[New-bugs-announce] [issue15897] zipimport.c doesn't check return value of fseek()

[Christian Heimes]

New submission from Christian Heimes:

The code im zipimport.c doesn't check the return value of fseek() in at least four places. The missing checks may hide issues with the file or file system.

Solution:
Check for -1 and return with an appropriate call to PyErr_SetFromErrno()
