Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-41903)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error during git archive invocation. A remote attacker can trick the victim into using the application against a specially crafted archive, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Integer overflow (CVE-ID: CVE-2022-23521)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insufficient validation of user-supplied input when parsing the .gitattributes attributes. A remote attacker can trick the victim into cloning a specially crafted repository and execute arbitrary code on the system.
3) 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.
4) Integer overflow (CVE-ID: CVE-2022-40303)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in parse.c when processing content when XML_PARSE_HUGE is set. 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.
5) Resource management error (CVE-ID: CVE-2022-40304)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in entities.c due to the way libxml2 handles reference cycles. The library does not anticipate that entity content can be allocated from a dict and clears it upon reference cycle detection by setting its first byte to zero. This can lead to memory corruption issues, such as double free errors and result in a denial of service.
6) Creation of Temporary File With Insecure Permissions (CVE-ID: CVE-2022-24823)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to usage of insecure permissions for temporary files. A local user can view contents of temporary files and gain access to sensitive information.
7) Error Handling (CVE-ID: CVE-2023-23931)
The vulnerability allows an attacker to misuse Python API.
The vulnerability exists due to a soundness bug within the Cipher.update_into function, which can allow immutable objects (such as bytes) to be mutated. A malicious programmer can misuse Python API to introduce unexpected behavior into the application.
8) Infinite loop (CVE-ID: CVE-2022-41881)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the HaProxyMessageDecoder when parsing a TLV with type of "PP2_TYPE_SSL". A remote attacker can pass a specially crafted message to consume all available system resources and cause denial of service conditions.
9) Resource exhaustion (CVE-ID: CVE-2023-24580)
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. A remote attacker can certain inputs to multipart forms, trigger memory exhaustion and perform a denial of service (DoS) attack.
10) HTTP response splitting (CVE-ID: CVE-2023-23936)
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not correctly process CRLF character sequences when handling HTTP "Host" header. 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.
11) Incorrect Regular Expression (CVE-ID: CVE-2023-24807)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when user-supplied input within the `Headers.set()` and `Headers.append()` methods. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
12) 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.
