Joshua Marquart updated XALANJ-2792:
------------------------------------
Description:
Recent Sonatype Lifecycle scans of Xalan 2.7.3 (and Xalan servicemix 2.7.3_3)
are being flagged as having LOW vulnerability CVE-2019-2981 due to improper
error handling within JAXP classes.
org.apache.xpath.compiler.Compiler will throw an unchecked StackOverflowError
under certain conditions.
Per the CVE summary, this has already been resolved by certain JRE releases of
JAXP, however cursory review of the existing releases of the classes from Xalan
show the compensating code was not applied to the embedded JAXP classes and
therefore have the potential to throw a StackOverflowError.
RedHat, for example, resolved it with their JRE per
[https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-2981] /
[https://hg.openjdk.org/jdk8u/jdk8u/jaxp/rev/6f9c0c731ab7]
OpenJDK resolved it here: [https://linux.oracle.com/errata/ELSA-2019-3128.html]
*Description from CVE*
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE
(component: JAXP). Supported versions that are affected are Java SE: 7u231,
8u221, 11.0.4 and 13; Java SE Embedded: 8u221. Difficult to exploit
vulnerability allows unauthenticated attacker with network access via multiple
protocols to compromise Java SE, Java SE Embedded. Successful attacks of this
vulnerability can result in unauthorized ability to cause a partial denial of
service (partial DOS) of Java SE, Java SE Embedded. Note: This vulnerability
applies to Java deployments, typically in clients running sandboxed Java Web
Start applications or sandboxed Java applets (in Java SE 8), that load and run
untrusted code (e.g., code that comes from the internet) and rely on the Java
sandbox for security. This vulnerability can also be exploited by using APIs in
the specified Component, e.g., through a web service which supplies data to the
APIs. CVSS 3.0 Base Score 3.7 (Availability impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
*Explanation*
Certain components within OpenJDK versions 7, 8, etc. are vulnerable to
improper handling of exceptions. Under some cases, an unauthenticated attacker
may be able to exploit this vulnerability to trigger a partial Denial of
Service (DoS).
