VUL-0: CVE-2016-2811, CVE-2016-2812: MozillaFirefox: Use-after-free and buffer overflow in Service Workers (MFSA 2016-42)
Last modified: 2020-04-05 18:21:22 UTC
https://www.mozilla.org/en-US/security/advisories/mfsa2016-42/ Security researcher Looben Yang reported two issues discovered in Service Workers using Address Sanitizer. The first of these is a use-after-free vulnerability caused by a ServiceWorkerInfo object being kept active beyond the life its owning registration. When it is later called through this registration, a use-after-free results. In the second issue, a race condition leading to a buffer overflow was found in the ServiceWorkerManager. This leads to a potentially exploitable crash when triggered.
