Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2022-32206)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insecure processing of compressed HTTP responses. A malicious server can send a specially crafted HTTP response to curl and perform a denial of service attack by forcing curl to spend enormous amounts of allocated heap memory, or trying to and returning out of memory errors.
2) Memory leak (CVE-ID: CVE-2022-2191)
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak when handling incorrect TLS connections. A remote attacker can force the application to leak memory and perform denial of service attack.
3) Resource exhaustion (CVE-ID: CVE-2022-25857)
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 when handling YAML files. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
4) Out-of-bounds read (CVE-ID: CVE-2022-1586)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary condition in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. A remote attacker can pass specially crafted data to the application, trigger out-of-bounds read error, gain access to sensitive information or perform a denial of service attack.
5) Buffer overflow (CVE-ID: CVE-2022-23218)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the svcunix_create() in the sunrpc module ib glibc. A remote attacker can pass specially crafted input to the application that is using the affected library version, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
