Description

This security bulletin contains information about 21 secuirty vulnerabilities.


1) OS Command Injection (CVE-ID: CVE-2022-48339)

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

The vulnerability exists due to improper input validation within the hfy-istext-command() function when parsing the "file" and "srcdir" parameters, if a file name or directory name contains shell metacharacter. A remote attacker can execute arbitrary OS commands on the target system.

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


2) Improper Certificate Validation (CVE-ID: CVE-2023-31486)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to missing verification of the TLS certificate. A remote attacker can perform MitM attack and trick the application into downloading a malicious file.

3) Buffer Underwrite ('Buffer Underflow') (CVE-ID: CVE-2023-31130)

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

The vulnerability exists due to a buffer underflow when using certain IPv6 addresses, such as 0::00:00:00/2". A local privileged user can trigger a boundary error and crash the service.


4) Buffer overflow (CVE-ID: CVE-2023-22745)

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

The vulnerability exists due to a boundary error in "Tss2_RC_SetHandler" and "Tss2_RC_Decode". A remote attacker 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.


5) Resource management error (CVE-ID: CVE-2023-5678)

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

The vulnerability exists due to improper management of internal resources within DH_generate_key() and DH_check_pub_key() functions. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


6) Information disclosure (CVE-ID: CVE-2023-4641)

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

The vulnerability exists due to an error in gpasswd(1), which fails to clean memory properly. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. A local user with enough access can retrieve the password from the memory.


7) Out-of-bounds write (CVE-ID: CVE-2023-4016)

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

The vulnerability exists due to a boundary error when processing untrusted input. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.


8) Resource management error (CVE-ID: CVE-2023-3817)

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

The vulnerability exists due to improper management of internal resources within the application when checking the long DH keys. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


9) Resource management error (CVE-ID: CVE-2023-3446)

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

The vulnerability exists due to improper management of internal resources within the DH_check(), DH_check_ex() and EVP_PKEY_param_check() function when processing a DH key or DH parameters. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


10) Integer overflow (CVE-ID: CVE-2022-48468)

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

The vulnerability exists due to integer overflow within parse_required_member() function. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.

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


11) OS Command Injection (CVE-ID: CVE-2022-48337)

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

The vulnerability exists due to improper input validation when parsing name of a source-code file in lib-src/etags.c. A remote attacker can trick the victim use the "etags -u *" command on the directory with attacker controlled content and execute arbitrary OS commands on the target system.



12) Resource exhaustion (CVE-ID: CVE-2023-44487)

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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

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


13) Out-of-bounds read (CVE-ID: CVE-2022-41862)

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

The vulnerability exists due to a boundary condition. A remote attacker can send an unterminated string during the establishment of Kerberos transport encryption, trigger an out-of-bounds read error and read contents of memory on the system.


14) Buffer overflow (CVE-ID: CVE-2022-4904)

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

The vulnerability exists due to a boundary error within the config_sortlist() function. A local user can trigger memory corruption and perform a denial of service (DoS) attack.


15) Resource exhaustion (CVE-ID: CVE-2022-3094)

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

The vulnerability exists due to application does not properly control consumption of internal resources when handling DNS updates. A remote attacker can trigger resource exhaustion by sending a flood of dynamic DNS updates.


16) Out-of-bounds read (CVE-ID: CVE-2020-22217)

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

The vulnerability exists due to a boundary condition within the ares_parse_soa_reply() function in ares_parse_soa_reply.c. A remote attacker can trigger an out-of-bounds read error and crash the application.


17) Path traversal (CVE-ID: CVE-2007-4559)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to improper validation of filenames in the tarfile module in Python. A remote attacker can create a specially crafted archive with symbolic links inside or filenames that contain directory traversal characters (e.g. "..") and overwrite arbitrary files on the system.


18) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-5870)

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

The vulnerability exists due to pg_cancel_backend rolse signals background workers, including the logical replication launcher, autovacuum workers and the autovacuum launcher. A remote privileged user can abuse this behavior and perform a denial of service (DoS) attack.


19) Integer overflow (CVE-ID: CVE-2023-5869)

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

The vulnerability exists due to integer overflow in array modification. A remote user can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.


20) Information disclosure (CVE-ID: CVE-2023-5868)

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

The vulnerability exists due to excessive data output by the application in the aggregate function calls when handling "unknown"-type arguments. A remote user can read parts of system memory.


21) SQL injection (CVE-ID: CVE-2023-39417)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data within the extension script @substitutions@, which uses @extowner@, @extschema@, or @extschema:...@ inside a quoting construct. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
