Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2017-12613)
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.The weakness exists due to an out-of-bounds array dereference in the apr_time_exp_get() function. A remote attacker can access prior out-of-bounds memory, reveal the contents of a different static heap value and read arbitrary files or cause the application to crash.
2) Out-of-bounds read (CVE-ID: CVE-2021-35940)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary condition in the "apr_time_exp*()" functions. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
Note, the vulnerability exists due to a missing patch for #VU9477 (CVE-2017-12613).
3) Integer overflow (CVE-ID: CVE-2022-24963)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the apr_encode() 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.
