Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Improper validation of integrity check value (CVE-ID: CVE-2022-29173)
The vulnerability allows a remote attacker to bypass expected security restrictions.
The vulnerability exists due to incorrect implementation of the client workflow for updating the metadata files for roles other than the root role. Checks for rollback attacks are not implemented correctly, as a result a remote attacker can force clients to install older versions of software that may contain security vulnerabilities.
2) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2021-40528)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to use of a broken or risky cryptographic algorithm in the ElGamal implementation. A remote attacker can gain unauthorized access to sensitive information on the system.
3) Heap-based buffer overflow (CVE-ID: CVE-2022-1621)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trick the victim to open a specially crafted file, 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.
4) Out-of-bounds read (CVE-ID: CVE-2022-1629)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to a boundary condition in find_next_quote() function. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error, perform a denial of service attack, modify memory, and execute arbitrary code.
5) Improper Authentication (CVE-ID: CVE-2022-22576)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error when re-using OAUTH2 connections for SASL-enabled protocols, such as SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only). libcurl may reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. As a result, a connection that is successfully created and authenticated with a user name + OAUTH2 bearer can subsequently be erroneously reused even for user + [other OAUTH2 bearer], even though that might not even be a valid bearer.
A remote attacker can exploit this vulnerability against applications intended for use in multi-user environments to bypass authentication and gain unauthorized access to victim's accounts.
6) Stack-based buffer overflow (CVE-ID: CVE-2022-25313)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in build_model. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Integer overflow (CVE-ID: CVE-2022-25314)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in copyString. 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.
8) Information disclosure (CVE-ID: CVE-2022-27774)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to curl attempts to follow redirects during authentication process and does not consider different port numbers or protocols to be separate authentication targets. If the web application performs redirection to a different port number of protocol, cURL will allow such redirection and will pass credentials. It could also leak the TLS SRP credentials this way.
By default, curl only allows redirects to HTTP(S) and FTP(S), but can be asked to allow redirects to all protocols curl supports.
9) Information disclosure (CVE-ID: CVE-2022-27776)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to curl can leak authentication or cookie header data during HTTP redirects to the same host but another port number. When asked to send custom headers or cookies in its HTTP requests, curl sends that set of headers only to the host which name is used in the initial URL, so that redirects to other hosts will make curl send the data to those. However, due to a flawed check, curl wrongly also sends that same set of headers to the hosts that are identical to the first one but use a different port number or URL scheme.
The vulnerability exists due to an incomplete fix for #VU10224 (CVE-2018-1000007).
10) Incorrect Implementation of Authentication Algorithm (CVE-ID: CVE-2022-27782)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the way libcurl handles previously used connections in a connection pool for subsequent transfers. Several TLS and SSH settings were left out from the configuration match checks, resulting in erroneous matches for different resources. As a result, libcurl can send authentication string from one resource to another, exposing credentials to a third-party.
11) Integer overflow (CVE-ID: CVE-2022-29824)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*). A remote attacker can pass specially crafted multi-gigabyte XML file to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
