Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2017-9047)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the xmlSnprintfElementContent function of XMLSoft libxml2 due to improper memory handling by the valid.c source code. A remote attacker can send a specially crafted XML file, trigger memory corruption and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.
2) Stack-based buffer overflow (CVE-ID: CVE-2017-9048)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the xmlSnprintfElementContent function of XMLSoft libxml2 due to improper bounds checking in the valid.c code. A remote attacker can send a specially crafted request, trigger stack-based buffer overflow condition and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.
3) Heap-based buffer over-read (CVE-ID: CVE-2017-9049)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the xmlDictComputeFastKey function of XMLSoft libxml2 due to improper bounds checking in the dict.c code. A remote attacker can send a specially crafted request, trigger heap-based buffer over-read condition and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.
4) Heap-based buffer over-read (CVE-ID: CVE-2017-9050)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the xmlDictAddString function of XMLSoft libxml2 due to improper bounds checking in the dict.c code.
