Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Improper Privilege Management (CVE-ID: CVE-2020-13938)
The vulnerability allows a local user to stop the service.
The vulnerability exists due to improper privilege management. A local user can on the Windows system can stop the Apache HTTP server service.
2) NULL pointer dereference (CVE-ID: CVE-2021-26691)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in mod_session. A a malicious backend server or SessionHeader can trigger a denial of service (DoS) condition.
3) NULL pointer dereference (CVE-ID: CVE-2021-34798)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can send a specially crafted HTTP request to the affected web server and perform a denial of service (DoS) attack.
4) Buffer overflow (CVE-ID: CVE-2021-3711)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in EVP_PKEY_decrypt() function within implementation of the SM2 decryption. A remote attacker can send specially crafted SM2 content for decryption to trigger a buffer overflow by 62 bytes and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Buffer overflow (CVE-ID: CVE-2021-44790)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing multipart content in mod_lua. A remote attacker can send a specially crafted HTTP request to the affected web server, trigger buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-22720)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests. 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.
7) Out-of-bounds write (CVE-ID: CVE-2022-23943)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in mod_sed. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
8) Infinite loop (CVE-ID: CVE-2022-0778)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the BN_mod_sqrt() function when processing an ASN.1 certificate that contains elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. A remote attacker can supply a specially crafted certificate to the TLS server or client, consume all available system resources and cause denial of service conditions.
