(1) CVE-2015-1819 / #782782
Florian Weimer from Red Hat reported an issue against libxml2, where a parser which uses libxml2 chokes on a crafted XML document, allocating gigabytes of data. This is a fine line issue between API misuse and a bug in libxml2. This issue got addressed in libxml2 upstream and the patch has been backported to libxml2 in squeeze-lts.
(2) #782985
Jun Kokatsu reported an out-of-bounds memory access in libxml2. By entering an unclosed html comment the libxml2 parser didn't stop parsing at the end of the buffer, causing random memory to be included in the parsed comment that was returned to the evoking application.
In the Shopify application (where this issue was originally discovered), this caused ruby objects from previous http requests to be disclosed in the rendered page.
(3) #783010
Michal Zalewski reported another out-of-bound reads issue in libxml2 that did not cause any crashes but could be detected under ASAN and Valgrind.");
