CVE-2011-3193

Publication date 15 June 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

Heap-based buffer overflow in the Lookup_MarkMarkPos function in the HarfBuzz module (harfbuzz-gpos.c), as used by Qt before 4.7.4 and Pango, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted font file.
