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

Releases

Packages

  • 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
Ubuntu 16.04

After a standard system update you need to restart your session to make
all the necessary changes.
