Description
This security bulletin contains information about 4 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2017-5130)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to heap-based buffer overflow in libxml2. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
2) Resource exhaustion (CVE-ID: CVE-2017-16932)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 6.9 [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]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in parser.c function due to improper handling of certain parameter entities. A remote attacker can supply specially constructed XML data, trigger resource exhaustion and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
3) Use-after-free error (CVE-ID: CVE-2017-15412)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to use-after-free error in libXML. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
4) Use-after-free (CVE-ID: CVE-2016-5131)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing vectors related to the XPointer range-to function. A remote attackers can cause a denial of service or execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
