Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Off-by-one (CVE-ID: CVE-2022-3821)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an off-by-one error within the format_timespan() function in time-util.c. A local user can trigger an off-by-one error and perform a denial of service (DoS) attack.
2) Integer overflow (CVE-ID: CVE-2022-47629)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the CRL signature parser. 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.
3) Integer overflow (CVE-ID: CVE-2022-42898)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to an integer overflow within the S4U2Proxy handler on 32-bit systems. A remote user can send specially crafted request to the KDC server, 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.
4) Resource management error (CVE-ID: CVE-2022-40304)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in entities.c due to the way libxml2 handles reference cycles. The library does not anticipate that entity content can be allocated from a dict and clears it upon reference cycle detection by setting its first byte to zero. This can lead to memory corruption issues, such as double free errors and result in a denial of service.
5) Integer overflow (CVE-ID: CVE-2022-40303)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in parse.c when processing content when XML_PARSE_HUGE is set. 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.
6) Improper Validation of Array Index (CVE-ID: CVE-2022-35737)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when handling an overly large input passed as argument to a C API. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
7) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-34903)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error in GnuPG, which allows signature spoofing via arbitrary injection into the status line. A remote attacker who controls the secret part of any signing-capable key or subkey in the victim's keyring, can take advantage of this flaw to provide a correctly-formed signature that some software, including gpgme, will accept to have validity and signer fingerprint chosen from the attacker.
8) Heap-based buffer overflow (CVE-ID: CVE-2022-33099)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The
vulnerability exists due to a boundary error in the luaG_runerror component. A remote attacker can send specially crafted data to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.
9) Buffer overflow (CVE-ID: CVE-2022-3786)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The
vulnerability exists due to a boundary error when processing the email
address field length inside a X.509 certificate. A remote attacker can supply a
specially crafted certificate to the application, trigger a buffer overflow and crash the application.
10) Heap-based buffer overflow (CVE-ID: CVE-2022-3715)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in valid_parameter_transform() function in GNU bash. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.
11) Buffer overflow (CVE-ID: CVE-2022-3602)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing the email address field inside X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a 4-byte buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that either a CA signs the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.
12) 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.
13) Double Free (CVE-ID: CVE-2022-2509)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within gnutls_pkcs7_verify() function when verifying the pkcs7 signatures. A remote attacker can pass specially crafted data to the application, trigger a double free error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
14) Out-of-bounds write (CVE-ID: CVE-2022-1304)
The vulnerability allows a local attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input. A local attacker can use a specially crafted filesystem, trigger out-of-bounds write and execute arbitrary code on the target system.
15) Input validation error (CVE-ID: CVE-2022-1271)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insufficient validation when processing filenames with two or more newlines. A remote attacker can force zgrep or xzgrep to write arbitrary files on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.
16) Off-by-one (CVE-ID: CVE-2021-46848)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an ETYPE_OK off-by-one error in asn1_encode_simple_der in Libtasn1. A remote attacker can pass specially crafted data to the application, trigger an off-by-one error and perform a denial of service (DoS) attack.
17) Configuration (CVE-ID: CVE-2023-0813)
The vulnerability allows a remote attacker to gain unauthorized access to the application.
The vulnerability exists due to an error in the authentication implementation. Setting Loki authToken configuration to DISABLE or HOST modes disables authentication. As a result, a remote attacker can gain unauthorized access to the OpenShift Console in an OpenShift cluster and obtain sensitive information.
