Bug#932491: python3-apt: segfault reading from lzma stream

Show all headers | View raw

Package: python3-apt
Version: 1.9.0
Severity: normal

The following script segfaults if python3-apt is installed, but
completes if not. Replacing lzma.open with open (and replacing
Sources.xz with Sources) also makes the segfault go away.  It seems to
be the same with python3-apt 1.8.4. I didn't check the python2 version
because lzma is (afaik) python3 only.

#!/usr/bin/python3
from debian.deb822 import Sources
import lzma

with lzma.open('Sources.xz', mode='rb') as f:
    for src in Sources.iter_paragraphs(f):
        package_name = src.get('Package')
        version = src.get('Version')
