libsolv vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10

Summary:

Libzip could be made to crash if it received specially crafted input.

Software Description:
- libsolv: A dependency solver using a satisfiablility algorithm

Details:

It was discovered that libsolv incorrectly handled certain malformed input. If
a
user or automated system were tricked into opening a specially crafted file,
applications that rely on libsolv could be made to crash, resulting in a denial
of service.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.10:
libsolv-tools 0.6.35-2ubuntu0.18.10.1
libsolv0 0.6.35-2ubuntu0.18.10.1
libsolvext0 0.6.35-2ubuntu0.18.10.1

After a standard system update you need to reboot your computer to make
all the necessary changes.
