Detail

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

- Ubuntu 17.10 - Ubuntu 16.04 LTS

Summary:

gcab could be made to crash or run programs if it opened a specially crafted file.

Software Description: - gcab: Microsoft Cabinet file manipulation tool

Details:

Richard Hughes discovered that gcab incorrectly handled certain malformed cabinet files. If a user or automated system were tricked into opening a specially crafted cabinet file, a remote attacker could use this issue to cause gcab to crash, resulting in a denial of service, or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 17.10:
gcab 0.7-4ubuntu0.1
libgcab-1.0-0 0.7-4ubuntu0.1

Ubuntu 16.04 LTS:

libgcab-1.0-0 0.7-1ubuntu0.1
