USN-3916-1: libsolv vulnerabilities

Releases

• Ubuntu 18.10

Packages

• 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.
