Description

This security bulletin contains information about 18 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2023-29499)

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. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


2) Double Free (CVE-ID: CVE-2023-39975)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the free_req_info(). A remote attacker send a specially crafted request to trigger a double free error and perform a denial of service (DoS) attack.


3) 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.


4) External control of file name or path (CVE-ID: CVE-2023-38546)

The vulnerability allows an attacker to inject arbitrary cookies into request.

The vulnerability exists due to the way cookies are handled by libcurl. If a transfer has cookies enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned version of the handle would instead store the file name as none (using the four ASCII letters, no quotes).

Subsequent use of the cloned handle that does not explicitly set a source to load cookies from would then inadvertently load cookies from a file named none - if such a file exists and is readable in the current directory of the program using libcurl.

5) Heap-based buffer overflow (CVE-ID: CVE-2023-38545)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the SOCKS5 proxy handshake. A remote attacker can trick the victim to visit a malicious website, trigger a heap-based 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 SOCKS5 proxy is used and that SOCKS5 handshake is slow (e.g. under heavy load or DoS attack).


6) Access of Uninitialized Pointer (CVE-ID: CVE-2023-36054)

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to the  _xdr_kadm5_principal_ent_rec() function in lib/kadm5/kadm_rpc_xdr.c does not validate the relationship between n_key_data and the key_data array count and frees an uninitialized pointer. A remote user can send a specially crafted request to the application and perform a denial of service (DoS) attack.


7) Resource exhaustion (CVE-ID: CVE-2023-32665)

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. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


8) Resource exhaustion (CVE-ID: CVE-2023-32611)

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 within the g_variant_byteswap() function. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


9) Buffer overflow (CVE-ID: CVE-2023-29491)

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing malformed data in a terminfo database file. A local user can trigger memory corruption and execute arbitrary code on the target system.



10) Resource exhaustion (CVE-ID: CVE-2023-44487)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.


11) 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.


12) Integer overflow (CVE-ID: CVE-2021-43618)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer overflow in mpz/inp_raw.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.


13) 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.


14) 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.


15) 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.


16) 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.


17) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-5528)

The vulnerability allows a remote user to escalate privileges on the system.

The vulnerability exists due to improper access restrictions. A remote user with ability to create pods and persistent volumes on Windows nodes can obtain admin privileges on those nodes.

The vulnerability affects Kubernetes clusters only, if they are using an in-tree storage plugin for Windows nodes.


18) Resource exhaustion (CVE-ID: CVE-2023-39325)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.
