Overview
Affected versions of this package are vulnerable to Denial of Service (DoS) due to improper exception handling by the GzipSource class when parsing a malformed gzip buffer.
This vulnerability can be exploited on the Okio client when handling a crafted GZIP archive.
PoC
val gzBuf: Buffer = Buffer()
try {
val gzByteString: ByteString = ("1f8b41ff424242424343ffff").decodeHex()
gzBuf.write(gzByteString)
val gz: GzipSource = GzipSource(gzBuf)
val sinkBuf: Buffer = Buffer()
gz.read(sinkBuf, 5)
}
catch(e: IOException) {
println("got error: " + e.toString())
}
Details
Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.
Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.
One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.
When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.
Two common types of DoS vulnerabilities:
High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.
Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm
wspackage
Remediation
Upgrade com.squareup.okio:okio to version 1.17.6, 3.4.0 or higher.

Overview
org.jetbrains.kotlin:kotlin-stdlib is a Kotlin Standard Library for JVM.
Affected versions of this package are vulnerable to Information Exposure. A Kotlin application using createTempDir or createTempFile and placing sensitive information within either of these locations would be leaking this information in a read-only way to other users also on this system.
Note: As of version 1.4.21, the vulnerable functions have been marked as deprecated. Due to still being usable, this advisory is kept as "unfixed".
