Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Open redirect (CVE-ID: CVE-2023-26159)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data within the url.parse() function. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
2) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2021-35937)
The vulnerability allows a local privileged user to escalate privileges on the system.
The vulnerability exist due to race condition. A local privileged user can bypass the checks that were introduced in response to CVE-2017-7500 and CVE-2017-7501, potentially gaining root privileges.
3) Link following (CVE-ID: CVE-2021-35938)
The vulnerability allows a local privileged user to escalate privileges on the system.
The vulnerability occurs when rpm sets the desired permissions and credentials after installing a file. A local privileged user can use this flaw to exchange the original file with a symbolic link to a security-critical file and escalate their privileges on the system.
4) Link following (CVE-ID: CVE-2021-35939)
The vulnerability allows a local privileged user to escalate privileges on the system.
The vulnerability exist due to fix for CVE-2017-7500 and CVE-2017-7501 was incomplete: the check was only implemented for the parent directory of the file to be created. A local privileged user who owns another ancestor directory could potentially use this flaw to gain root privileges.
5) Resource management error (CVE-ID: CVE-2023-3446)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the DH_check(), DH_check_ex() and EVP_PKEY_param_check() function when processing a DH key or DH parameters. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
6) Resource management error (CVE-ID: CVE-2023-3817)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when checking the long DH keys. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
7) Resource management error (CVE-ID: CVE-2023-5678)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within DH_generate_key() and DH_check_pub_key() functions. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
8) Out-of-bounds read (CVE-ID: CVE-2023-7104)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the sessionReadRecord() function in ext/session/sqlite3session.c when processing a corrupt changeset. A remote user can send a specially crafted request to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.
9) Out-of-bounds read (CVE-ID: CVE-2023-39615)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the xmlSAX2StartElement() function in /libxml2/SAX2.c. A remote attacker can pass specially crafted XML input to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
10) Inadequate encryption strength (CVE-ID: CVE-2023-48795)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.
The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.
11) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2024-0553)
The vulnerability allows a remote attacker to perform timing attack.
The vulnerability exists due to the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. A remote attacker can perform timing sidechannel attack in RSA-PSK key exchange.
Note, the vulnerability exists due to incomplete fox for #VU83316 (CVE-2023-5981).
