Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-36090)
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 processing ZIP archives. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Out-of-bounds write (CVE-ID: CVE-2020-36518)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can trigger out-of-bounds write and cause a denial of service condition on the target system.
3) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-32215)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to llhttp parser in the http module does not correctly handle multi-line Transfer-Encoding headers. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
4) Improper input validation (CVE-ID: CVE-2020-35169)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The vulnerability exists due to improper input validation. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.
5) Deserialization of Untrusted Data (CVE-ID: CVE-2022-25647)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to insecure input validation when processing serialized data passed to writeReplace() method. A remote attacker can pass specially crafted data to the application and perform a denial of service attack.
6) Integer overflow (CVE-ID: CVE-2022-28327)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to integer overflow in the Golang's library crypto/elliptic. A remote attacker can send a specially crafted scalar input longer than 32 bytes to cause P256().ScalarMult or P256().ScalarBaseMult to panic and perform a denial of service attack.
7) Off-by-one (CVE-ID: CVE-2021-23017)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an off-by-one error within the ngx_resolver_copy() function when processing DNS responses. A remote attacker can trigger an off-by-one error, write a dot character (‘.’, 0x2E) out of bounds in a heap allocated buffer and execute arbitrary code on the system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
The vulnerability can be triggered by a DNS response in reply to a DNS request from nginx when the resolver primitive is configured. A specially crafted packet allows overwriting the least significant byte of next heap chunk metadata with 0x2E.
