HP’s Zero Day Initiative has released four new zero days in Internet Explorer Mobile that can lead to remote code execution on Windows Phones.
The four vulnerabilities originally were reported to Microsoft as affecting IE on the desktop, and later on it was discovered that they also affected IE Mobile on Windows Phones. Microsoft has patched all of the vulnerabilities in the desktop version of the browser, but the bugs remain open on IE Mobile. ZDI’s original advisories on these flaws said that they were zero days on Internet Explorer, as well. The company updated the advisories late Thursday to reflect the fact that the bugs only affect IE Mobile.
