Description
This security bulletin contains information about 1 vulnerability.
1) Buffer overflow (CVE-ID: CVE-2018-7648)
CWE-ID: CWE-120 - Buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists in the mj2/opj_mj2_extract.c source code file due to insufficient length checks of output prefixes. A local attacker can send a specially crafted prefix, which contains 50 or more characters via the command line, trigger buffer overflow condition and cause the service to crash.
