CVE-2010-3444: Fribidi GNU Fribidi

High severity, CVSS 7.5. EPSS: 4.5% chance of exploitation in the next 30 days.

Buffer overflow in the log2vis_utf8 function in pyfribidi.c in GNU FriBidi 0.19.1, 0.19.2, and possibly other versions, as used in PyFriBidi 0.10.1, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted Arabic UTF-8 string that causes original 2-byte UTF-8 sequences to be transformed into 3-byte sequences.

Affected products

  • Fribidi GNU Fribidi: version 0.19.1 only; version 0.19.2 only
  • Kobi Zamir Pyfribidi: version 0.10.1 only
