Package        : uwsgi
Version        : 1.2.3+dfsg-5+deb7u2
CVE ID         : CVE-2018-6758
Debian Bug     : 889753

It was discovered that the uwsgi_expand_path function in utils.c in
Unbit uWSGI, an application container server, has a stack-based buffer
overflow via a large directory length that can cause a
denial-of-service (application crash) or stack corruption.

For Debian 7 "Wheezy", these problems have been fixed in version
1.2.3+dfsg-5+deb7u2.

We recommend that you upgrade your uwsgi packages.
