2) 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.
3) Out-of-bounds write (CVE-ID: CVE-2022-28737)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to a boundary error in the handle_image() function when shim tries to load and execute crafted EFI executables. A local privileged user can trigger an out-of-bounds write error and bypass secure boot protection mechanism.
4) Use-after-free (CVE-ID: CVE-2022-28736)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to a use-after-free error in the grub_cmd_chainloader() function in chainloader command. A local privileged user can trigger a use-after-free error and bypass secure boot protection mechanism.
5) Insufficient verification of data authenticity (CVE-ID: CVE-2022-28735)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to shim_lock verifier allows non-kernel files to be loaded on shim-powered secure boot systems. A local privileged user can load unverified modules into GRUB and bypass secure boot protection mechanism.
6) Out-of-bounds write (CVE-ID: CVE-2022-28734)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing split HTTP headerst. A remote attacker can send specially crafted traffic to the affected system, trigger an out-of-bounds write and execute arbitrary code on the target system.
7) Integer underflow (CVE-ID: CVE-2022-28733)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow when processing IP packets within the grub_net_recv_ip4_packets() function. A remote attacker can send specially crafted network traffic to the affected system, trigger an integer underflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) 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.
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) 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.
11) 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.
12) Incorrect authorization (CVE-ID: CVE-2022-24450)
The vulnerability allows a remote user to escalate privileges on the system.
The vulnerability exists due to misusing the "dynamically provisioned sandbox accounts" feature. A remote user can take advantage of its valid account and switch over to another existing account without further authentication to obtain the privileges of the System account.
13) 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.
14) 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.
15) 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.
16) 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.
17) Input validation error (CVE-ID: CVE-2022-1271)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insufficient validation when processing filenames with two or more newlines. A remote attacker can force zgrep or xzgrep to write arbitrary files on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.
18) 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.
19) Integer underflow (CVE-ID: CVE-2021-3697)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to integer underflow within the JPEG reader. A local privileged user can trigger an integer underflow and bypass secure boot protection mechanism.
20) Out-of-bounds write (CVE-ID: CVE-2021-3696)
The vulnerability allows a local privileged user to bypass implemented security restrictions.
The vulnerability exists due to a boundary error when handling Huffman tables in the PNG reader. A local privileged user can pass specially crafted PNG image to the application, trigger an out-of-bounds write error and potentially bypass secure boot protection mechanism.
21) Out-of-bounds write (CVE-ID: CVE-2021-3695)
The vulnerability allows a local privileged user to bypass implemented security restrictions.
The vulnerability exists due to a boundary error when processing PNG grayscale images. A local privileged user can pass specially crafted PNG image to the application, trigger an out-of-bounds write error and potentially bypass secure boot protection mechanism.
22) Buffer Over-read (CVE-ID: CVE-2020-28915)
The vulnerability allows a local user with physical access to perform a denial of service attack.
The vulnerability exists due to an out-of-bounds (OOB) memory access flaw in fbcon_get_font() function in drivers/video/fbdev/core/fbcon.c in fbcon driver module in the Linux kernel. A local user with special user privilege and with physical access can gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information.
