SB2022120108 - Multiple vulnerabilities in IBM Watson Discovery for IBM Cloud Pak for Data

Description

This security bulletin contains information about 2 vulnerabilities.

1) Integer overflow (CVE-ID: CVE-2022-3515)

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

The vulnerability exists due to integer overflow within the CRL parser in libksba. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

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

2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-34903)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to an error in GnuPG, which allows signature spoofing via arbitrary injection into the status line. A remote attacker who controls the secret part of any signing-capable key or subkey in the victim's keyring, can take advantage of this flaw to provide a correctly-formed signature that some software, including gpgme, will accept to have validity and signer fingerprint chosen from the attacker.
