Security Bulletin

Summary

The MD5 "SLOTH" vulnerability on TLS 1.2 affects IBM Notes.

Vulnerability Details

CVEID: CVE-2015-7575

DESCRIPTION: The TLS protocol could allow weaker than expected security caused
by a collision attack when using the MD5 hash function for signing a 
ServerKeyExchange message during a TLS handshake. An attacker could exploit 
this vulnerability using man-in-the-middle techniques to impersonate a TLS 
server and obtain credentials.

CVSS Base Score: 7.1

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109415 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N)

Affected Products and Versions

IBM Notes 9.0.1 Fix Pack 3 Interim Fix 2 through 9.0.1 Fix Pack 5.

NOTE: Since this vulnerability involves TLS 1.2, neither IBM Notes 9.0 nor IBM
Notes 8.5.x are affected.

Remediation/Fixes

The Notes SLOTH vulnerability is tracked as SPR KLYHA5YRVP and a fix is 
introduced in the following releases:

IBM Notes 9.0.1 Fixpack 5 IF 2 (for Windows)

IBM Notes 9.0.1 Fixpack 5 IF 1 (for Linux)

IBM Notes 64-bit 9.0.1 IF1 (for Mac 64-bit platform)

For Fix download links, refer to the following technote:

Notes & Domino 9.0.1 Fix Packs and Interim Fixes - 
http://www.ibm.com/support/docview.wss?uid=swg21657963

Customers who remain on the following releases may open a Service Request with
IBM Support and reference SPR KLYHA5YRVP for a custom hotfix:

IBM Notes 9.0.1 Fix Pack 3 IF3 and later

IBM Notes 9.0.1 Fix Pack 4 and all Interim Fixes

You should verify applying this fix does not cause any compatibility issues. 
The fix disables MD5 signature hash by default. If you change the default 
setting after applying the fix, you will expose yourself to the attack 
described above. IBM recommends that you review your entire environment to 
identify other areas where you have enabled the MD5 signature hash and take 
appropriate mitigation and remediation

Security Bulletin

Summary

This security bulletin details libpng related security vulnerabilities and 
fixes available in IBM Notes.

Vulnerability Details

CVEID: CVE-2015-7981

DESCRIPTION: libpng could allow a remote attacker to obtain sensitive 
information, caused by an out-of-bounds read in the png_convert_to_rfc1123 
function. An attacker could exploit this vulnerability to obtain sensitive 
information.

CVSS Base Score: 5.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/107740 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2015-8126

DESCRIPTION: libpng is vulnerable to a buffer overflow, caused by improper 
bounds checking by the png_set_PLTE() and png_get_PLTE() functions. By 
persuading a victim to open a specially-crafted PNG file, a remote attacker 
could overflow a buffer and execute arbitrary code on the system.

CVSS Base Score: 7.8

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/108010 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID: CVE-2015-8540

DESCRIPTION: libpng is vulnerable to a buffer overflow, caused by a read 
underflow in png_check_keyword in pngwutil.c. By sending an overly long 
argument, a remote attacker could overflow a buffer and execute arbitrary code
on the system or cause the application to crash.

CVSS Base Score: 9.8

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109219 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE- 2015-8472

DESCRIPTION: libpng is vulnerable to a buffer overflow, caused by improper 
bounds checking by the png_get_PLTE() and png_set_PLTE() functions. By 
persuading a victim to open a specially crafted PNG image, a remote attacker 
could overflow a buffer and execute arbitrary code on the system or cause the
application to crash.

CVSS Base Score: 6.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/109392 for the current 
score
