Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-48303)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the from_header() function in list.c when handling V7 archives. A remote attacker can trick the victim to open a specially crafted V7 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) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-23914)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to state issues when handling multiple requests, which results in ignoring HSTS support. A remote attacker can perform MitM attack.3) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-23915)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to state issues when handling multiple transfers in parallel, which results in ignoring HSTS support. A remote attacker can perform MitM attack.4) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-23916)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect implementation of the "chained" HTTP compression algorithms, where the number of links in the decompression chain was limited for each header instead of the entire request. A remote attacker can send a specially crafted compressed HTTP request with numerous headers and perform a denial of service (DoS) attack.
