Several security vulnerabilities were found in icedtea-web, an implementation of the Java Network Launching Protocol (JNLP).

CVE-2019-10181

 It was found that in icedtea-web executable code could be injected
 in a JAR file without compromising the signature verification. An
 attacker could use this flaw to inject code in a trusted JAR. The
 code would be executed inside the sandbox.

CVE-2019-10182

 It was found that icedtea-web did not properly sanitize paths from
 <jar/> elements in JNLP files. An attacker could trick a victim
 into running a specially crafted application and use this flaw to
 upload arbitrary files to arbitrary locations in the context of the
 user.

CVE-2019-10185

It was found that icedtea-web was vulnerable to a zip-slip attack
during auto-extraction of a JAR file. An attacker could use this
flaw to write files to arbitrary locations. This could also be used
to replace the main running application and, possibly, break out of
the sandbox.
