Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) 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.
2) 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.
3) OS Command Injection (CVE-ID: CVE-2022-48337)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when parsing name of a source-code file in lib-src/etags.c. A remote attacker can trick the victim use the "etags -u *" command on the directory with attacker controlled content and execute arbitrary OS commands on the target system.
4) OS Command Injection (CVE-ID: CVE-2022-48339)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation within the hfy-istext-command() function when parsing the "file" and "srcdir" parameters, if a file name or directory name contains shell metacharacter. A remote attacker can execute arbitrary OS commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-3153)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper rate limitation in the service monitor MAC. A remote attacker can perform a denial of service attack against deployments with CoPP enabled and properly configured.
6) 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.
7) Improper certificate validation (CVE-ID: CVE-2023-28321)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to improper certificate validation when matching wildcards in TLS certificates for IDN names. A remote attacker crate a specially crafted certificate that will be considered trusted by the library.
Successful exploitation of the vulnerability requires that curl is built to use OpenSSL, Schannel or Gskit.
8) Improper Certificate Validation (CVE-ID: CVE-2023-31486)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to missing verification of the TLS certificate. A remote attacker can perform MitM attack and trick the application into downloading a malicious file.9) 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).
none - if such a file exists and is readable in the current directory of the program using libcurl. Remediation
