Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Use-after-free vulnerability in Google Chrome before 13.0.782.107 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to HTML range handling.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Use-after-free vulnerability in Google Chrome versions prior to 13.0.782.107 allows remote attackers to cause denial of service or possibly execute arbitrary code via crafted vectors related to HTML range handling. The flaw occurs when the browser attempts to access memory that has already been freed during HTML range object manipulation.

MitigationUpdate Google Chrome to version 13.0.782.107 or later. Organizations should deploy browser updates through their patch management infrastructure and verify that affected installations are remediated.
