CVE-2016-2052: Multiple unspecified vulnerabilities in HarfBuzz before 1.0.6, as used in Google Chrome before 48.0.2564.82, allow attackers to cause a…
Noroxi assessment
Priority: Monitor (action score 30/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.95% (FIRST EPSS); higher than 62% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- Fixed version: harfbuzz (Debian:12) 1.2.6-1; chromium-browser (Red Hat:rhel_extras:6) 0:48.0.2564.82-1.el6; chromium-browser-debuginfo (Red Hat:rhel_extras:6) 0:48.0.2564.82-1.el6.
Low priority for now. Upgrade to harfbuzz (Debian:12) 1.2.6-1; chromium-browser (Red Hat:rhel_extras:6) 0:48.0.2564.82-1.el6; chromium-browser-debuginfo (Red Hat:rhel_extras:6) 0:48.0.2564.82-1.el6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Multiple unspecified vulnerabilities in HarfBuzz before 1.0.6, as used in Google Chrome before 48.0.2564.82, allow attackers to cause a denial of service or possibly have other impact via crafted data, as demonstrated by a buffer over-read resulting from an inverted length check in hb-ot-font.cc, a different issue than CVE-2015-8947.
