Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Infinite loop (CVE-ID: CVE-2022-0778)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the BN_mod_sqrt() function when processing an ASN.1 certificate that contains elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. A remote attacker can supply a specially crafted certificate to the TLS server or client, consume all available system resources and cause denial of service conditions.
2) Integer underflow (CVE-ID: CVE-2022-28733)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow when processing IP packets within the grub_net_recv_ip4_packets() function. A remote attacker can send specially crafted network traffic to the affected system, trigger an integer underflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Out-of-bounds write (CVE-ID: CVE-2022-28734)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing split HTTP headerst. A remote attacker can send specially crafted traffic to the affected system, trigger an out-of-bounds write and execute arbitrary code on the target system.
4) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2021-40528)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to use of a broken or risky cryptographic algorithm in the ElGamal implementation. A remote attacker can gain unauthorized access to sensitive information on the system.
