Package: schroot
Version: 1.6.10-1+b1
Severity: important
Tags: upstream patch
Hi!
The attached patch fixes an infinite allocation loop inside the
passwd::query_name, passwd::query_uid, group::query_gid and
group::query_name functions.
Current code simply fails with std::bad_alloc on any error,
because it always retries with a bigger buffer.
