CVE-2025-0677 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 6.4 Medium |
A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grub_malloc() may be called with a smaller value than needed. When further reading the data from the disk into the buffer, the grub_ufs_lookup_symlink() function will write past the end of the allocated size. An attack can leverage this by crafting a malicious filesystem, and as a result, it will corrupt data stored in the heap, allowing for arbitrary code execution used to by-pass secure boot mechanisms. | ||||
CVE-2025-0624 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 7.6 High |
A flaw was found in grub2. During the network boot process, when trying to search for the configuration file, grub copies data from a user controlled environment variable into an internal buffer using the grub_strcpy() function. During this step, it fails to consider the environment variable length when allocating the internal buffer, resulting in an out-of-bounds write. If correctly exploited, this issue may result in remote code execution through the same network segment grub is searching for the boot information, which can be used to by-pass secure boot protections. | ||||
CVE-2024-45777 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 6.7 Medium |
A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in grub_gettext_getstr_from_position() may overflow, leading to a Out-of-bound write. This issue can be leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the circumvention of secure boot protections. | ||||
CVE-2025-1118 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 4.4 Medium |
A flaw was found in grub2. Grub's dump command is not blocked when grub is in lockdown mode, which allows the user to read any memory information, and an attacker may leverage this in order to extract signatures, salts, and other sensitive information from the memory. | ||||
CVE-2023-0466 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Jboss Core Services and 1 more | 2025-02-19 | 5.3 Medium |
The function X509_VERIFY_PARAM_add0_policy() is documented to implicitly enable the certificate policy check when doing certificate verification. However the implementation of the function does not enable the check which allows certificates with invalid or incorrect policies to pass the certificate verification. As suddenly enabling the policy check could break existing deployments it was decided to keep the existing behavior of the X509_VERIFY_PARAM_add0_policy() function. Instead the applications that require OpenSSL to perform certificate policy check need to use X509_VERIFY_PARAM_set1_policies() or explicitly enable the policy check by calling X509_VERIFY_PARAM_set_flags() with the X509_V_FLAG_POLICY_CHECK flag argument. Certificate policy checks are disabled by default in OpenSSL and are not commonly used by applications. | ||||
CVE-2023-0179 | 4 Canonical, Fedoraproject, Linux and 1 more | 15 Ubuntu Linux, Fedora, Linux Kernel and 12 more | 2025-02-19 | 7.8 High |
A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution. | ||||
CVE-2024-45775 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 5.2 Medium |
A flaw was found in grub2 where the grub_extcmd_dispatcher() function calls grub_arg_list_alloc() to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parse_option() function, leading grub to crash or, in some rare scenarios, corrupt the IVT data. | ||||
CVE-2024-45776 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 6.7 Medium |
When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections. | ||||
CVE-2025-26465 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 6.8 Medium |
A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. | ||||
CVE-2024-45781 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 6.7 Medium |
A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure boot protections. | ||||
CVE-2024-45783 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-19 | 4.4 Medium |
A flaw was found in grub2. When failing to mount an HFS+ grub, the hfsplus filesystem driver doesn't properly set an ERRNO value. This issue may lead to a NULL pointer access. | ||||
CVE-2024-56201 | 1 Redhat | 8 Ansible Automation Platform, Discovery, Enterprise Linux and 5 more | 2025-02-18 | 7.3 High |
Jinja is an extensible templating engine. In versions on the 3.x branch prior to 3.1.5, a bug in the Jinja compiler allows an attacker that controls both the content and filename of a template to execute arbitrary Python code, regardless of if Jinja's sandbox is used. To exploit the vulnerability, an attacker needs to control both the filename and the contents of a template. Whether that is the case depends on the type of application using Jinja. This vulnerability impacts users of applications which execute untrusted templates where the template author can also choose the template filename. This vulnerability is fixed in 3.1.5. | ||||

CVE-2023-0465 | 2 Openssl, Redhat | 4 Openssl, Enterprise Linux, Jboss Core Services and 1 more | 2025-02-18 | 5.3 Medium |
Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function. | ||||
CVE-2025-0622 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-02-18 | 6.4 Medium |
A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vulnerability. If correctly exploited, this vulnerability may result in arbitrary code execution, eventually allowing the attacker to bypass secure boot protections. | ||||
CVE-2023-0664 | 4 Fedoraproject, Microsoft, Qemu and 1 more | 4 Fedora, Windows, Qemu and 1 more | 2025-02-18 | 7.8 High |
A flaw was found in the QEMU Guest Agent service for Windows. A local unprivileged user may be able to manipulate the QEMU Guest Agent's Windows installer via repair custom actions to elevate their privileges on the system. | ||||
CVE-2022-3787 | 1 Redhat | 2 Device-mapper-multipath, Enterprise Linux | 2025-02-18 | 7.8 High |
A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, exploited alone or in conjunction with CVE-2022-41973. Local users that are able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This issue occurs because an attacker can repeat a keyword, which is mishandled when arithmetic ADD is used instead of bitwise OR. This could lead to local privilege escalation to root. | ||||
CVE-2022-36059 | 2 Matrix, Redhat | 4 Javascript Sdk, Enterprise Linux, Rhel E4s and 1 more | 2025-02-18 | 8.2 High |
matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 19.4.0 events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. This issue has been fixed in matrix-js-sdk 19.4.0 and users are advised to upgrade. Users unable to upgrade may mitigate this issue by redacting applicable events, waiting for the sync processor to store data, and restarting the client. Alternatively, redacting the applicable events and clearing all storage will often fix most perceived issues. In some cases, no workarounds are possible. | ||||
