Description

This security bulletin contains information about 7 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2023-27539)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to insufficient validation of user-supplied input when parsing HTTP headers. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


2) Cross-site scripting (CVE-ID: CVE-2023-28120)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Green


The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in ActiveSupport when calling a new bytesplice method on a SafeBuffer. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


3) Deadlock (CVE-ID: CVE-2022-4269)

CWE-ID: CWE-833 - Deadlock

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to an error in the Linux kernel Traffic Control (TC) subsystem. A local user can use a specific network configuration (redirecting egress packets to ingress using TC action "mirred") to trigger a CPU soft lockup.


4) Stack-based buffer overflow (CVE-ID: CVE-2022-4378)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear


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

The vulnerability exists due to a boundary error within the __do_proc_dointvec() function. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.


5) Use-after-free (CVE-ID: CVE-2023-0266)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber


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

The vulnerability exists due to a use-after-free error within the snd_ctl_elem_read() function in the Linux kernel sound subsystem. A local user can trigger a use-after-free error and execute arbitrary code on the system.

Note, the vulnerability is being actively exploited in the wild.


6) Inadequate Encryption Strength (CVE-ID: CVE-2023-0361)

CWE-ID: CWE-326 - Inadequate Encryption Strength

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error in the TLS RSA key exchange. A remote attacker can perform Bleichenbacher oracle attack and decrypt information.


7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-0386)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear


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

The vulnerability exists due to unauthorized access to execution of setuid files in OverlayFS subsystem when copying a capable file from a nosuid mount into another mount. A local user can execute arbitrary code with root privileges.
