Description

This security bulletin contains information about 18 secuirty vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2022-1897)

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

The vulnerability exists due to Illegal memory access and leads to an out-of-bounds write vulnerability in the vim_regsub_both() function. A local attacker can trick the victim into opening a specially crafted file, leading to a system crash or code execution.


2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-34903)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to an error in GnuPG, which allows signature spoofing via arbitrary injection into the status line. A remote attacker who controls the secret part of any signing-capable key or subkey in the victim's keyring, can take advantage of this flaw to provide a correctly-formed signature that some software, including gpgme, will accept to have validity and signer fingerprint chosen from the attacker.


3) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-32208)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to improper handling of message verification failures when performing FTP transfers secured by krb5. A remote attacker can perform MitM attack and manipulate data.


4) Resource exhaustion (CVE-ID: CVE-2022-32206)

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

The vulnerability exists due to insecure processing of compressed HTTP responses. A malicious server can send a specially crafted HTTP response to curl and perform a denial of service attack by forcing curl to spend enormous amounts of allocated heap memory, or trying to and returning out of memory errors.


5) Path traversal (CVE-ID: CVE-2022-29154)

The vulnerability allows a remote server to perform directory traversal attacks.

The vulnerability exists due to input validation error within the rsync client  when processing file names. A remote malicious server overwrite arbitrary files in the rsync client target directory and subdirectories on the connected peer.


6) Missing Encryption of Sensitive Data (CVE-ID: CVE-2022-2097)

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

The vulnerability exists due to an error in AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation. Under specific circumstances OpenSSL does not encrypt the entire message and can reveal sixteen bytes of data that was preexisting in the memory that wasn't written. A remote attacker can gain access to potentially sensitive information.



7) OS Command Injection (CVE-ID: CVE-2022-2068)

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

The vulnerability exists due to improper input validation in the c_rehash script distributed by some operating systems. A remote attacker with ability to pass data to c_rehash script can and execute arbitrary OS commands with the privileges of the script.

The vulnerability exists due to incomplete fix for #VU62765 (CVE-2022-1292).


8) Out-of-bounds read (CVE-ID: CVE-2022-1927)

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

The vulnerability exists due to Illegal memory access and leads to a buffer over-read vulnerability in the utf_ptr2char() function. A local attacker can trick the victim into opening a specially crafted file, trigger out-of-bounds read error and execute arbitrary code on the system.


9) Out-of-bounds write (CVE-ID: CVE-2022-1785)

The vulnerability allows a remote attacker to execute arbitrary code

The vulnerability exists due to a boundary error when processing untrusted input in vim_regsub_both() function. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.


10) Buffer overflow (CVE-ID: CVE-2022-24675)

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

The vulnerability exists in the Golang's library encoding/pem. A remote attacker can send to victim a large (more than 5 MB) PEM input to cause a stack overflow in Decode and perform a denial of service (DoS) attack.


11) Out-of-bounds read (CVE-ID: CVE-2022-1586)

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

The vulnerability exists due to a boundary condition in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. A remote attacker can pass specially crafted data to the application, trigger out-of-bounds read error, gain access to sensitive information or perform a denial of service attack.


12) OS Command Injection (CVE-ID: CVE-2022-1292)

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

The vulnerability exists due to improper input validation in the c_rehash script distributed by some operating systems. A remote attacker with ability to pass data to c_rehash script can and execute arbitrary OS commands with the privileges of the script.



13) CRLF injection (CVE-ID: CVE-2022-0391)

The vulnerability allows a remote attacker to inject arbitrary data in server response.

The vulnerability exists due to insufficient validation of attacker-supplied data within the urllib.parse module in Python. A remote attacker can pass specially crafted data to the application containing CR-LF characters and modify application behavior.


14) OS Command Injection (CVE-ID: CVE-2015-20107)

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

The vulnerability exists due to improper input validation in the mailcap module, which does not escape characters into commands discovered in the system mailcap file. A remote unauthenticated attacker can pass specially crafted data to the applications that call mailcap.findmatch with untrusted input and execute arbitrary OS commands on the target system.



15) Resource exhaustion (CVE-ID: CVE-2022-30631)

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 in Reader.Read method when handling an archive that contains a large number of concatenated 0-length compressed files. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


16) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-29526)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to the Faccessat function can incorrectly report that a file is accessible, when called with a non-zero flags parameter. An attacker can bypass implemented security restrictions.


17) Integer overflow (CVE-ID: CVE-2022-28327)

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

The vulnerability exists due to integer overflow in the Golang's library crypto/elliptic. A remote attacker can send a specially crafted scalar input longer than 32 bytes to cause P256().ScalarMult or P256().ScalarBaseMult to panic and perform a denial of service attack.


18) Incorrect Regular Expression (CVE-ID: CVE-2022-24921)

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

The vulnerability exists due to an error in regexp.Compile in Go. A remote attacker can pass specially crafted input to the application and perform regular expression denial of service (ReDoS) attack.
