Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2018-1000518)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when handling compressed data. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Covert Timing Channel (CVE-ID: CVE-2020-25659)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

python-cryptography 3.2 is vulnerable to Bleichenbacher timing attacks in the RSA decryption API, via timed processing of valid PKCS#1 v1.5 ciphertext.


3) Integer overflow (CVE-ID: CVE-2020-36242)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow when processing certain sequences of update calls to symmetrically encrypt multi-GB values. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Resource management error (CVE-ID: CVE-2021-22569)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the application. protobuf-java allowes the interleaving of com.google.protobuf.UnknownFieldSet fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses. A remote attacker can trick the victim into passing specially crafted data to the application and perform a denial of service attack.


5) Improper input validation (CVE-ID: CVE-2021-22570)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the Server: Compiling (protobuf) component in MySQL Server. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.


6) Improper input validation (CVE-ID: CVE-2022-1941)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the Connector/Python (Python) component in MySQL Connectors. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.


7) Input validation error (CVE-ID: CVE-2022-3171)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input containing multiple instances of non-repeated embedded messages with repeated or unknown fields. A remote attacker can cause objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses.
