Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2021-38561)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition. A remote attacker can pass specially crafted input to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2022-21698)
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 within method label cardinality. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) OS Command Injection (CVE-ID: CVE-2015-20107)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation in the mailcap module, which does not escape characters into commands discovered in the system mailcap file. A remote unauthenticated attacker can pass specially crafted data to the applications that call mailcap.findmatch with untrusted input and execute arbitrary OS commands on the target system.
4) CRLF injection (CVE-ID: CVE-2022-0391)
The vulnerability allows a remote attacker to inject arbitrary data in server response.
The vulnerability exists due to insufficient validation of attacker-supplied data within the urllib.parse module in Python. A remote attacker can pass specially crafted data to the application containing CR-LF characters and modify application behavior.
5) Information disclosure (CVE-ID: CVE-2022-21123)
The vulnerability allows an attacker to gain access to potentially sensitive information.
The vulnerability exists in Intel processors due to excessive data output when DirectPath I/O (PCI-Passthrough) is utilized. An attacker (both local and remote) with administrative access to a virtual machine that has an attached DirectPath I/O (PCI-Passthrough) device can obtain information stored in physical memory about the hypervisor or other virtual machines that reside on the same host.
6) Information disclosure (CVE-ID: CVE-2022-21125)
The vulnerability allows an attacker to gain access to potentially sensitive information.
The vulnerability exists in Intel processors due to excessive data output when DirectPath I/O (PCI-Passthrough) is utilized. An attacker (both local and remote) with administrative access to a virtual machine that has an attached DirectPath I/O (PCI-Passthrough) device can obtain information stored in physical memory about the hypervisor or other virtual machines that reside on the same host.
7) Information disclosure (CVE-ID: CVE-2022-21166)
The vulnerability allows an attacker to gain access to potentially sensitive information.
The vulnerability exists in Intel processors due to excessive data output when DirectPath I/O (PCI-Passthrough) is utilized. An attacker (both local and remote) with administrative access to a virtual machine that has an attached DirectPath I/O (PCI-Passthrough) device can obtain information stored in physical memory about the hypervisor or other virtual machines that reside on the same host.
8) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-34903)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error in GnuPG, which allows signature spoofing via arbitrary injection into the status line. A remote attacker who controls the secret part of any signing-capable key or subkey in the victim's keyring, can take advantage of this flaw to provide a correctly-formed signature that some software, including gpgme, will accept to have validity and signer fingerprint chosen from the attacker.
