Summary
Vulnerabilities in libpng affect Rational DOORS.
Vulnerability Details
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: 8.800
CVSS Temporal Score (X-Force Link): 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
CVE-ID:
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: 6.300
CVSS Temporal Score (X-Force Link): see

Affected Products and Versions
Rational DOORS: 9.3.0.0 - 9.3.0.10, 9.4.0.0 - 9.4.0.4, 9.5.0.0 - 9.5.0.4,

The following Rational DOORS components are affected:
Rational DOORS desktop client
Rational DOORS database server
Rational DOORS interoperation server
Remediation/Fixes
Upgrade to the fix pack that corresponds to the version of Rational DOORS
that you are running, as shown in the following table. Upgrade the Rational
DOORS client, the Rational DOORS database server, and the Rational DOORS
interoperation server. You should verify applying this fix does not cause any
compatibility issues.
Rational DOORS version Upgrade to fix pack
9.3 9.3.0.12
9.3.0.1 - 9.3.0.11
9.4 9.4.0.6
9.4.0.1 - 9.4.0.5
9.5 9.5.0.6
9.5.0.1 - 9.5.0.5
9.5.1 9.5.1.7
9.5.1.1 - 9.5.1.6
9.5.2 9.5.2.6
9.5.2.1 - 9.5.2.5
9.6.0 9.6.0.5
9.6.0.1 - 9.6.0.4
9.6.1 9.6.1.5
9.6.1.1 - 9.6.1.4
For Rational DOORS version 9.2.x and earlier, IBM recommends upgrading to a
fixed, supported version/release/platform of the product.
If you are using Rational DOORS Web Access, after you upgrade, but before you
start the Rational DOORS Web Access server, edit the core configuration file
and set the required version of the interoperation server to the version of the
fix pack upgrade, as described in this procedure.
Procedure:
To edit the Rational DOORS Web Access core configuration file, open the
festival.xml file, which is in the server\festival\config directory.
Add the following line in the
<f:properties>
section:
<f:property name="interop.version" value="9.n.n.n"/>
Replace "9.n.n.n" with the version of the fix pack upgrade: 9.3.0.12, 9.4.0.6,
9.5.0.6,9.5.1.7, 9.5.2.6, 9.6.0.5, or 9.6.1.5.
Save and close the file.
After this revision, only the specified version of the interoperation server
can access the Rational DOORS database.
