Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU15910
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-19198
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition or execute arbitrary code on the target system.
The vulnerability exists due to out-of-bounds write in the uriComposeQuery* and uriComposeQueryEx* functions, as defined in the UriQuery.csource code file. A local attacker can send a specially request that submits malicious input, trigger memory corruption to cause a DoS condition or execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
