CVE-2019-8611· NVD / CVE Program· CNA apple

Multiple memory corruption issues were addressed with improved memory handling.

Noroxi assessment

Priority: Monitor (action score 38/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 8.4% (FIRST EPSS); higher than 94.9% 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: webkit2gtk (Debian:12) 2.24.1-1; webkit2gtk3 (openSUSE:Leap 15.0) 2.24.2-lp151.2.3.1; webkit2gtk3 (SUSE:Linux Enterprise Desktop 12 SP4) 2.24.2-2.44.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to webkit2gtk (Debian:12) 2.24.1-1; webkit2gtk3 (openSUSE:Leap 15.0) 2.24.2-lp151.2.3.1; webkit2gtk3 (SUSE:Linux Enterprise Desktop 12 SP4) 2.24.2-2.44.1 or later.

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
