Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2022-31030)
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 ExecSync API. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
3) 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.
4) Resource exhaustion (CVE-ID: CVE-2022-41723)
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 in the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.
5) Cross-site scripting (CVE-ID: CVE-2023-3978)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
6) Resource exhaustion (CVE-ID: CVE-2022-23471)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in containerd CRI stream server when handling terminal resize events. A remote user can request a TTY and force it to fail by sending a faulty command and exhaust memory on the host.
7) Cross-site scripting (CVE-ID: CVE-2023-39318)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data within the html/template package when handling HMTL-like "<!--" and "-->" comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. A remote attacker can pass specially crafted input to the application and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
8) Out-of-bounds write (CVE-ID: CVE-2023-4016)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when processing untrusted input. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
9) Resource exhaustion (CVE-ID: CVE-2023-25153)
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 importing an OCI image. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
10) Cross-site scripting (CVE-ID: CVE-2023-39319)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists within the html/template package caused by improperly applied rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. A remote attacker can pass specially crafted input to the application and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
11) 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.
12) Improper Privilege Management (CVE-ID: CVE-2023-25173)
The vulnerability allows a local user to escalate privileges.
The vulnerability exists due to improper privilege management where supplementary groups are not set up properly inside a container. A local user can use supplementary group access to bypass primary group restrictions and compromise the container.
13) Improper Certificate Validation (CVE-ID: CVE-2023-29409)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to verifying certificate chains containing large RSA keys is slow. A remote attacker can cause a client/server to expend significant CPU time verifying signatures.
14) 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.
15) Information disclosure (CVE-ID: CVE-2023-4641)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to an error in gpasswd(1), which fails to clean memory properly. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. A local user with enough access can retrieve the password from the memory.
