Oracle Linux: CVE-2021-31292: ELSA-2021-4319: compat-exiv2-026 security update (MODERATE) (Multiple Advisories)
Description
An integer overflow in CrwMap::encode0x1810 of Exiv2 0.27.3 allows attackers to trigger a heap-based buffer overflow and cause a denial of service (DOS) via crafted metadata. A flaw was found in exiv2. A integer wraparound in the CrwMap:encode0x1810 function leads to memcpy call with a very large size allowing an attacker, who can provide a malicious image, to crash an application which uses the exiv2 library. The highest threat from this vulnerability is to service availability.
