[Touch-packages] [Bug 1773316] Re: Object of different cache passed as argument to apt_pkg.DepCache method
JFTR, in case anyone is looking at this: The fix for xenial and trusty has been merged into the fix for 1737441, and was fixed there, as the regression that manifested in this bug due to the fix for 1737441 never manifested in those releases, as there was no upload with just that fix. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python-apt in Ubuntu. https://bugs.launchpad.net/bugs/1773316 Title: Object of different cache passed as argument to apt_pkg.DepCache method Status in python-apt package in Ubuntu: Fix Released Status in update-manager package in Ubuntu: Won't Fix Status in update-manager source package in Trusty: Confirmed Status in update-manager source package in Xenial: Confirmed Status in python-apt source package in Bionic: Fix Released Status in update-manager source package in Bionic: Won't Fix Status in python-apt source package in Cosmic: Fix Released Status in update-manager source package in Cosmic: Won't Fix Bug description: [Impact] python-apt 1.6 raises an exception when objects of an old cache are passed to a apt_pkg.DepCache methods for a different cache.

[Touch-packages] [Bug 1773316] Re: Object of different cache passed as argument to apt_pkg.DepCache method
** Description changed: - == xenial / trusty == - [Impact] - Some applications, like unattended-upgrades or update-manager, reopen the apt cache. They also keep around old apt.Package objects however, and operate on them after reopening. Under the hood, this means that apt_pkg.Package objects belonging to an old cache are passed to a new cache. - - APT relies on the ID of the package (it's position in the cache) for - it's operation. So if a package has ID 0 in the old cache, and a - different package has ID 0 in the new cache, performing operations on - the old package would perform it on the new package. If the old - package's ID is out of bounds in the new cache, the behavior is - undefined - it's an out of bounds array access. - - [Test case] - The attached test case has a list of packages 0-9, a-z; stores the package "z" into a variable, then reopens the cache. It then marks z for deletion. This either segfaults or does nothing; when it should mark z for deletion. - - More test cases like this are in the autopkgtest. - - [Regression potential] - The initial fix introduced bug 1780099, there might be similar bugs lurking. However, these bugs would have been undefined behavior before and might have caused segmentation faults or did the wrong thing. It seems likely that any regression cannot possibly be worse than the current state. - - == bionic+ === - [Impact] python-apt 1.6 raises an exception when objects of an old cache are passed to a apt_pkg.DepCache methods for a different cache.
