CVE-2016-1526
HighSummary
The TtfUtil:LocaLookup function in TtfUtil.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.6.1, incorrectly validates a size value. This allows remote attackers to obtain sensitive information or cause a denial of service via a crafted Graphite smart font.
Risk Assessment
This vulnerability may lead to the disclosure of sensitive data or application crashes, potentially affecting the availability of services within the organization.
Recommendation
It is recommended to update Mozilla Firefox to the latest version to mitigate this vulnerability and to monitor systems for potential exploitation attempts.
