#VU12154 Heap-based buffer overflow in HDF5 - CVE-2016-4332
Published: April 25, 2018
Vulnerability identifier: #VU12154
Vulnerability risk: Low
CVSSv4.0: 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-2016-4332
CWE-ID: CWE-122
Exploitation vector: Local access
Exploit availability:
No public exploit available
Vulnerable software:
HDF5
HDF5
Software vendor:
HDF Group
HDF Group
Description
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to library's failure to check if certain message types support a particular flag and the library can cast the structure to an alternative structure and then assign to fields that aren't supported by the message type and the library can write outside the bounds of the heap buffer. A local attacker can trigger heap-based buffer overflow and execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
