Use-after-free vulnerability in WebCore in WebKit in Google Chrome before 5.0.375.70 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via vectors involving remote fonts in conjunction with shadow DOM trees, aka rdar problem 8007953. NOTE: this might overlap CVE-2010-1771.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
