pyelftools is a Library for analyzing ELF files and DWARF debugging information

Affected versions of this package are vulnerable to Denial of Service (DoS). This can occur when parsing an ELF file whose e_shentsize is zero, and e_shnum is larger than the actual number of entries in the section header table. The function ELFFile.iter_sections iterates over i in range(self['e_shnum']) and yields sections at file offset self['e_shoff'] + i * self['e_shentsize']. If e_shentsize is zero this will return the first section over and over again.

How to fix Denial of Service (DoS)?

There is no fixed version for pyelftools.
