CVE-2019-5796· NVD / CVE Program· CNA Chrome

Data race in extensions guest view in Google Chrome prior to 73.0.3683.75 allowed a remote attacker to potentially exploit heap corruption v

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 4.6% (FIRST EPSS); higher than 91.4% 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. Special conditions such as timing or configuration are required.
  • Fixed version: chromium (Debian:12) 73.0.3683.75-1; chromium (Debian:9) 73.0.3683.75-1~deb9u1; chromium (openSUSE:Leap 15.0) 73.0.3683.75-lp150.206.1.

Low priority for now. Upgrade to chromium (Debian:12) 73.0.3683.75-1; chromium (Debian:9) 73.0.3683.75-1~deb9u1; chromium (openSUSE:Leap 15.0) 73.0.3683.75-lp150.206.1 or later.

Proof of concept available

A public proof of concept or detection signature exists. Exploit knowledge is out there; don't delay patching.

Evidence

  • Exploit-DB entry ×1

Noroxi does not host or link to exploit code. Metasploit module names and Nuclei template ids are shown (names, not code); Exploit-DB entries and PoC repositories are given as counts only.

Patch and commit links

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

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.
