Description Andrej Nemec 2017-05-19 04:01:41 EDT

libxml2 is vulnerable to a heap-based buffer over-read in the xmlDictComputeFastKey function in dict.c. This vulnerability causes programs that use libxml2 to crash. This vulnerability exists because of an incomplete fix for libxml2 Bug 759398.

oss-security report suggests this is the same as CVE-2017-9050, as exactly the same patch is proposed and the stack trace passes through the same function chain.
