2019-07 Security Bulletin: Juniper Secure Analytics (JSA): Multiple vulnerabilities resolved in JSA 7.3.2 Patch 1
Article ID: JSA10950
Last Updated: 10 Jul 2019
Version: 1.0
Product Affected:
These issues affect the Juniper Secure Analytics (JSA) Series.
Problem:
Multiple vulnerabilities have been resolved in the Juniper Secure Analytics
(JSA) 7.3.2 Patch 1 release by fixing the vulnerabilities and updating the
third party software packages included with JSA.
The important security issues resolved include:
CVE CVSS Summary
5.3 (
CVSS:3.0/ Juniper JSA 7.3 discloses sensitive information to
CVE-2018-1729 AV:N/AC:L/ unauthorized users. The information can be used to
PR:N/UI:N/ mount further attacks on the system.
S:U/C:L/I:N/
A:N )
7.5 ( python before versions 2.7.15, 3.4.9, 3.5.6rc1,
CVSS:3.0/ 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic
CVE-2018-1060 AV:N/AC:L/ backtracking in pop3lib's apop() method. An
PR:N/UI:N/ attacker could use this flaw to cause denial of
S:U/C:N/I:N/ service.
A:H )
7.5 ( python before versions 2.7.15, 3.4.9, 3.5.6rc1,
CVSS:3.0/ 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic
CVE-2018-1061 AV:N/AC:L/ backtracking in the difflib.IS_LINE_JUNK method. An
PR:N/UI:N/ attacker could use this flaw to cause denial of
S:U/C:N/I:N/ service.
A:H )
7.8 ( An AVX-512-optimized implementation of the mempcpy
CVSS:3.0/ function in the GNU C Library (aka glibc or libc6)
CVE-2018-11237 AV:L/AC:L/ 2.27 and earlier may write data beyond the target
PR:L/UI:N/ buffer, leading to a buffer overflow in
S:U/C:H/I:H/ __mempcpy_avx512_no_vzeroupper.
A:H )
Constructed ASN.1 types with a recursive definition
6.5 ( (such as can be found in PKCS7) could eventually
CVSS:3.0/ exceed the stack given malicious input with
AV:N/AC:L/ excessive recursion. This could result in a Denial
CVE-2018-0739 PR:N/UI:R/ Of Service attack. There are no such structures
S:U/C:N/I:N/ used within SSL/TLS that come from untrusted
A:H ) sources so this is considered safe. Fixed in
OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in
OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).
During key agreement in a TLS handshake using a DH
(E) based ciphersuite a malicious server can send a
7.5 ( very large prime value to the client. This will
CVSS:3.0/ cause the client to spend an unreasonably long
CVE-2018-0732 AV:N/AC:L/ period of time generating a key for this prime
PR:N/UI:N/ resulting in a hang until the client has finished.
S:U/C:N/I:N/ This could be exploited in a Denial Of Service
A:H ) attack. Fixed in OpenSSL 1.1.0i-dev (Affected
1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev
(Affected 1.0.2-1.0.2o).
Solution:
The issues listed above have been resolved in JSA: 7.3.2 Patch 1, and all
subsequent releases.
These issues are being tracked as PR 1445427 which is visible on the Customer
Support website.
Workaround:
There are no known workarounds for this issue, however, limiting access to only
trusted administrators from trusted administrative networks or hosts would
minimize the risk.
