Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2023-45230)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary within a long server ID option in DHCPv6 client. A remote attacker on the local network can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Buffer overflow (CVE-ID: CVE-2023-45235)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling Server ID option from a DHCPv6 proxy Advertise message. A remote attacker on the local network can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-39539)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper access restrictions. An local user can load a malicious PNG Logo file and compromise the affected system.4) Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) (CVE-ID: CVE-2023-45237)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a predictable TCP Initial Sequence Number. A remote attacker can gain unauthorized access to sensitive information on the system.
5) Infinite loop (CVE-ID: CVE-2023-45233)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing a PadN option in the Destination Options header of IPv6. A remote attacker can consume all available system resources and cause denial of service conditions.
6) Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) (CVE-ID: CVE-2023-45236)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a predictable TCP Initial Sequence Number. A remote attacker on the local network can gain unauthorized access to sensitive information on the system.
7) Out-of-bounds read (CVE-ID: CVE-2023-45231)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when processing Neighbor Discovery Redirect message. A remote attacker on the local network can trigger an out-of-bounds read error and read contents of memory on the system.
8) Buffer overflow (CVE-ID: CVE-2023-45234)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing DNS Servers option from a DHCPv6 Advertise message. A remote attacker on the local network can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Integer overflow (CVE-ID: CVE-2022-36763)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to integer overflow within the Tcg2MeasureGptTable() function when reading untrusted input from the disk. A local user can set up a malicious GPT table to trigger an integer overflow and overwrite code from UEFI applications.
10) Out-of-bounds read (CVE-ID: CVE-2023-45229)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when processing the IA_NA or IA_TA option in a DHCPv6 Advertise message. A remote attacker on the local network can trigger an out-of-bounds read error and read contents of memory on the system.
11) Infinite loop (CVE-ID: CVE-2023-45232)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing unknown options in the Destination Options header of IPv6. A remote attacker can consume all available system resources and cause denial of service conditions.
12) Input validation error (CVE-ID: CVE-2024-34163)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient validation of user-supplied input. A local user can execute arbitrary code with elevated privileges.
