How we can reliably check unsigned Release files is another question, and not urgent anyway, as it should have no dramatic effect (we could check that it is a valid RFC-822 section, but that's a bit too long to write) --- apt-pkg/acquire-item.cc | 45 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) (limited to 'apt-pkg') diff --git a/apt-pkg/acquire-item.cc b/apt-pkg/acquire-item.cc index 6785b4e1b..6df915d8e 100644 --- a/apt-pkg/acquire-item.cc +++ b/apt-pkg/acquire-item.cc @@ -271,6 +271,14 @@ void pkgAcqSubIndex::Done(string Message,unsigned long Size,string Md5Hash, /*{{ string FinalFile = _config->FindDir("Dir::State::lists")+URItoFileName(Desc.URI);
