Description
This security bulletin contains information about 1 vulnerability.
1) Memory corruption (CVE-ID: CVE-2016-2570)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the Edge Side Includes (ESI) parser due to improper checking of buffer limits during XML parsing. A remote attacker can use a specially crafted XML document, related to esi/CustomParser.cc and esi/CustomParser.h, as demonstrated by a crafted HTTP Vary header, trigger assertion failure and daemon exit and cause the service to crash.
