Description

This security bulletin contains information about 15 secuirty vulnerabilities.


1) 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.


2) 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).


3) 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.


4) Information disclosure (CVE-ID: CVE-2023-45803)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to urllib3 does not remove the HTTP request body when redirecting HTTP response using status codes 301, 302, or 303, after the request had its method changed from one that could accept a request body (e.g. from POST to GET). A remote attacker can gain access to potentially sensitive information.


5) Information disclosure (CVE-ID: CVE-2023-43804)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to urllib does not strip the "Cookie" HTTP header during cross-origin HTTP redirects. A remote attacker can gain unauthorized access to sensitive information.


6) 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.


7) Input validation error (CVE-ID: CVE-2023-27043)

The vulnerability allows a remote attacker to bypass filtration.

The vulnerability exists due to insufficient validation of user-supplied input when parsing email address with a special character. A remote attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain.


8) 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.


9) Resource exhaustion (CVE-ID: CVE-2023-49568)

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 handling responses from a Git server. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


10) 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.


11) 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.


12) 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.


13) 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.


14) 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.


15) Path traversal (CVE-ID: CVE-2023-49569)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can overwrite arbitrary files on the system. Applications are only affected if they are using the ChrootOS, which is the default when using "Plain" versions of Open and Clone funcs (e.g. PlainClone).
