Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2021-30560)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the Blink XSLT component in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger use-after-free error and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Input validation error (CVE-ID: CVE-2023-22809)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists within the sudoedit (aka -e) feature due to insufficient validation of user-supplied input passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR). The problem exists because a user-specified editor may contain a "--"
argument that defeats a protection mechanism, e.g., an EDITOR='vim --
/path/to/extra/file' value. A local user can append arbitrary entries to the list of files to process and escalate privileges on the system.
3) Incorrect Regular Expression (CVE-ID: CVE-2022-42969)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation in Subversion repository caused by a mishandled InfoSvnCommand argument. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
4) Incorrect Regular Expression (CVE-ID: CVE-2022-40899)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation when processing the Set-Cookie header. A remote attacker can send a specially crafted HTTP request to the application and perform a regular expression denial of service (ReDoS) attack.
5) Type Confusion (CVE-ID: CVE-2023-0286)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.
In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
6) Use-after-free (CVE-ID: CVE-2023-0215)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
7) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2022-4304)
The vulnerability allows a remote attacker to obtain sensitive information.
The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.
To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.
8) Integer overflow (CVE-ID: CVE-2022-47629)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the CRL signature parser. A remote attacker can pass specially crafted data to the application, trigger an integer overflow 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-2022-25147)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the apr_base64() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Link following (CVE-ID: CVE-2023-23946)
The vulnerability allows an attacker to compromise the affected system.
The vulnerability exists due to application allows to overwrite files outside the working tree via the "git apply" command. A remote attacker can trick the victim to run the affected command against a malicious or compromised repository and overwrite arbitrary files on the system.
11) Link following (CVE-ID: CVE-2023-22490)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insecure processing of symbolic links when using local clone optimization. Git will abort local clones whose source `$GIT_DIR/objects` directory
contains symbolic links, however the `objects` directory itself may still be a
symbolic link. A remote attacker can trick the victim into using the local clone optimization to exfiltrate arbitrary files from the victim's system.
12) HTTP response splitting (CVE-ID: CVE-2022-37436)
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not correctly process CRLF character sequences within the mod_proxy module. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
13) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-36760)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests in mod_proxy_ajp. A remote attacker can send a specially crafted HTTP request to the web server and smuggle arbitrary HTTP headers to the AJP server it forwards requests to.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
14) Buffer overflow (CVE-ID: CVE-2006-20001)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the mod_dav module when handling HTTP requests. A remote attacker can send a specially crafted HTTP request, trigger a one byte buffer overflow and perform a denial of service (DoS) attack.
