SOL16898: PKCS #7 vulnerability CVE-2015-1790
Security AdvisorySecurity Advisory
Original Publication Date: 07/07/2015
Description
The PKCS7_dataDecodefunction in crypto/pkcs7/pk7_doit.c in OpenSSL before
0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b
allows remote attackers to cause a denial of service (NULL pointer dereference
and application crash) via a PKCS#7 blob that uses ASN.1 encoding and lacks
inner EncryptedContent data. (CVE-2015-1790)
Impact
An attacker may be able to craft malformed ASN.1-encoded PKCS#7 blobs with
missing content and trigger a NULL pointer dereference on parsing.
Note: This vulnerability is exploitable only through the BIG-IP control plane
(non-Traffic Management Microkernel (TMM) related tasks).
Status
F5 Product Development has assigned ID 527637 (BIG-IP and BIG-IQ), ID 529766
(Enterprise Manager), ID 410742 (ARX), and ID 528809 (FirePass) to this
vulnerability, and has evaluated the currently supported releases for
potential vulnerability.
To determine if your release is known to be vulnerable, the components or
features that are affected by the vulnerability, and for information about
releases or hotfixes that address the vulnerability, refer to the following

*The BIG-IP data plane is not vulnerable to this CVE. The control plane is
only vulnerable when a locally authenticated attacker uses the OpenSSL command
line tool.
Note: As of February 17, 2015, AskF5 Security Advisory articles include the
Severity value. Security Advisory articles published before this date do not
list a Severity value.
Recommended Action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the listed version is older than the version you are
currently running, or if the table does not list any version in the column,
then no upgrade candidate currently exists.
F5 responds to vulnerabilities in accordance with the Severity values
published in the previous table. The Severity values and other security
vulnerability parameters are defined in SOL4602: Overview of the F5 security
vulnerability response policy.
To mitigate this vulnerability, F5 recommends that you expose management
access only on trusted networks.
