========================================================================== Ubuntu Security Notice USN-4179-1 November 07, 2019
fribidi vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.10 - Ubuntu 19.04
Summary:
Applications using FriBidi could be made to crash or run programs as your login if it displayed specially crafted text.
Software Description: - fribidi: Free Implementation of the Unicode BiDi algorithm (utility)
Details:
Alex Murray discovered a stack-based buffer overflow when handling a large number of unicode isolate directives. An attacker could use this to cause 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 19.10: libfribidi0 1.0.5-3.1ubuntu0.19.10.1
Ubuntu 19.04: libfribidi0 1.0.5-3.1ubuntu0.19.04.1
In general, a standard system update will make all the necessary changes.
