Excessive memory allocation in OpenSSL

1) Excessive memory allocation

EUVDB-ID: #VU641

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-2109

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote user to cause excessive memory allocation on the target system.

The weakness exists during reading ASN.1 data by d2i_CMS_bio() function. A short invalid encoding leads to distribution of large amounts of memory for excessive resources or exhausting memory.

Successful exploitation of the vulnerability may result in excessive memory allocation.

Mitigation

Update 1.0.1 to 1.01t.
Update 1.0.2. to 1.0.2h.
