Description

This security bulletin contains information about 10 secuirty vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2023-25165)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to insecure usage of the getHostByName template function. A remote attacker can use DNS exfiltration technique to gain access to sensitive information.


2) Integer overflow (CVE-ID: CVE-2021-43618)

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

The vulnerability exists due to integer overflow in mpz/inp_raw.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.


3) Off-by-one (CVE-ID: CVE-2022-3821)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to an off-by-one error within the format_timespan() function in time-util.c. A local user can trigger an off-by-one error and perform a denial of service (DoS) attack.



4) Improper Privilege Management (CVE-ID: CVE-2022-4415)

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to improper privilege management when handling coredumps in coredump/coredump.c. A local user can gain access to sensitive information.

The vulnerability affects systems with libacl support.


5) Out-of-bounds read (CVE-ID: CVE-2023-7104)

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the sessionReadRecord() function in ext/session/sqlite3session.c when processing a corrupt changeset. A remote user can send a specially crafted request to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.


6) Improper Privilege Management (CVE-ID: CVE-2023-26604)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper privilege management for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.


7) 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.


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) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2024-0553)

The vulnerability allows a remote attacker to perform timing attack.

The vulnerability exists due to the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. A remote attacker can perform timing sidechannel attack in RSA-PSK key exchange.

Note, the vulnerability exists due to incomplete fox for #VU83316 (CVE-2023-5981).


10) Reachable Assertion (CVE-ID: CVE-2024-0567)

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

The vulnerability exists due to a reachable assertion when verifying a certificate chain with a cycle of cross signatures. A remote attacker can pass a specially crafted certificate to the application and perform a denial of service (DoS) attack.
