Vulnerability details
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Multiple use-after-free vulnerabilities in libxml2 2.9.0 and possibly other versions might allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to the (1) htmlParseChunk and (2) xmldecl_done functions, as demonstrated by a buffer overflow in the xmlBufGetInputBase function.
