Description
This security bulletin contains information about 1 vulnerability.
1) Information disclosure (CVE-ID: CVE-2017-14064)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to an issue with using strdup in ext/json/ext/generator/generator.c during a JSON generate call. A remote attacker can send a specially crafted request, stop strdup after encountering a '' byte, returning a pointer to a string of length zero, which is not the length stored in space_len and expose arbitrary memory.
Successful exploitation of the vulnerability results in information disclosure.
