Security Bulletin

This security bulletin contains information about 13 vulnerabilities.

1) Cryptographic issues

EUVDB-ID: #VU29460

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2020-12402

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to recover the secret primes.

During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.

Mitigation

Update the affected packages.

CVE-ID: CVE-2020-12420

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when trying to connect to a STUN server. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a race condition that causes the use-after-free of a pointer and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

8) Improper Certificate Validation

EUVDB-ID: #VU29457

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2020-12421

CWE-ID: CWE-295 - Improper Certificate Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to disable installed Add-Ons.

The vulnerability exists due to Add-On updates do not respect the same certificate trust rules as software updates. When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date silently without notification to the user.

Mitigation

Update the affected packages.

Description

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

The vulnerability exists due to integer overflow within the nsJPEGEncoder::emptyOutputBuffer function when processing JPEG images. A remote attacker can create a specially crafted JPEG image, trick the victim into visiting a web page with such an image, trigger integer overflow and execute arbitrary code on the target system.

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