Upstream patches applied in 2.9.2-r2. CVE: The xmlParseConditionalSections function in parser.c in libxml2 does not properly skip intermediary entities when it stops parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted XML data, a different vulnerability than CVE-2015-7941. Once again, not sure why this is counted as a common package. Re-designating to B3. GLSA Vote: No |
