Ubuntu Security Notice USN-3398-1
21st August, 2017
graphite2 vulnerabilities
A security issue affects these releases of Ubuntu and its
derivatives:
- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Summary
graphite2 could be made to crash or run programs if it opened a specially
crafted font.
Software description
- graphite2
– Font rendering engine for Complex Scripts
Details
Holger Fuhrmannek and Tyson Smith discovered that graphite2 incorrectly
handled certain malformed fonts. If a user or automated system were tricked
into opening a specially-crafted font file, a remote attacker could use
this issue to cause graphite2 to crash, resulting in a denial of service,
or possibly execute arbitrary code.
