Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-37434)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing a large gzip header within inflateGetHeader in inflate.c. A remote attacker can pass a specially crafted file to the affected application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-36521)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to allocation of resources without limits or throttling. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Resource exhaustion (CVE-ID: CVE-2023-35921)
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 specially crafted Ethernet frames. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
4) Resource exhaustion (CVE-ID: CVE-2023-35920)
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 specially crafted IP packets. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Type Confusion (CVE-ID: CVE-2023-0286)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.
In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
6) Use-after-free (CVE-ID: CVE-2023-0215)
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 BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
7) Path traversal (CVE-ID: CVE-2022-48285)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to insufficient sanitization of user-supplied in the loadAsync() method. A remote attacker can pass a specially crafted ZIP archive to the application and overwrite arbitrary files on the system.
8) Input validation error (CVE-ID: CVE-2022-36946)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the nfqnl_mangle() function in net/netfilter/nfnetlink_queue.c in the Linux kernel when processing IPv6 packets. A remote attacker can send specially crafted packets to the system and perform a denial of service (DoS) attack.
9) Out-of-bounds write (CVE-ID: CVE-2019-14196)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error within the nfs_lookup_reply() function in net/nfs.c. A remote attacker can create a specially crafted data to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.
10) Buffer overflow (CVE-ID: CVE-2022-30767)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the nfs_lookup_reply() function in net/nfs.c. A remote attacker can pass specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Note, the vulnerability exists due to incomplete fix for CVE-2019-14196.
11) Double Free (CVE-ID: CVE-2022-4450)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the PEM_read_bio_ex() function. A remote attacker can pass specially crafted PEM file to the application, trigger a double free error and perform a denial of service (DoS) attack.
12) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2022-4304)
The vulnerability allows a remote attacker to obtain sensitive information.
The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.
To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.
13) Memory leak (CVE-ID: CVE-2022-1012)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient randomization in the net/ipv4/tcp.c when calculating port offsets in Linux kernel cause by small table perturb size. A remote attacker can cause memory leak and gain access to sensitive information.
14) Resource exhaustion (CVE-ID: CVE-2021-46828)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to library improperly handles idle TCP connections. A remote attacker can exhaust the file descriptors of a process that uses libtirpc and perform a denial of service (DoS) attack.
