Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2022-2175)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in ex_getln.c. 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.
2) Use-after-free (CVE-ID: CVE-2022-2526)
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 on_stream_io() and dns_stream_complete() functions in resolved-dns-stream.c, which do not increment the reference counting for the DnsStream object. A remote attacker can send to the system specially crafted DNS responses, trigger a use-after-free error and perform a denial of service (DoS) attack.
3) Use-after-free (CVE-ID: CVE-2022-40674)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the doContent() function in xmlparse.c. A remote attacker can pass specially crafted input to the application that is using the affected library, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
4) Integer overflow (CVE-ID: CVE-2022-3515)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the CRL parser in libksba. 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.
