Summary

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
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.

For Debian 8 "Jessie", these problems have been fixed in version
1.5.3-1+deb8u1.
