**Name of the Vulnerable Software and Affected Versions** sudo versions prior to 1.9.17p3 **Description** In ptrace-based intercept mode, the software fails to apply intercept policy checks to the `execveat` system call. This allows users who are permitted to run specific commands to execute denied programs by calling `execveat` directly or through `fexecve`, which bypasses policy enforcement and logging. **Recommendations** Update to version 1.9.17p3 or later.

**Name of the Vulnerable Software and Affected Versions** OpenSSL (affected versions not specified) **Description** A NULL pointer dereference can occur in a CMP client application when processing a crafted CMP response. An attacker controlling a CMP server or acting as a man-in-the-middle can send a CRMF CertRepMessage containing an EncryptedValue structure where the `symmAlg` field includes an algorithm OID but lacks a parameters field. This leads to an application crash and a Denial of Service. This issue affects applications that process untrusted CMP/CRMF messages. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** PostgreSQL versions prior to 18.4 PostgreSQL versions prior to 17.10 PostgreSQL versions prior to 16.14 PostgreSQL versions prior to 15.18 PostgreSQL versions prior to 14.23 **Description** Symlink following in `pg basebackup` plain format and in `pg rewind` allows an origin superuser to overwrite local files, such as '/var/lib/postgres/.bashrc', which can lead to the hijacking of the operating system account. This issue has practical implications if actions are taken between the execution of these commands and the server start, such as moving files to a different virtual machine or snapshotting the virtual machine. **Recommendations** Update to version 18.4 or later. Update to version 17.10 or later. Update to version 16.14 or later. Update to version 15.18 or later. Update to version 14.23 or later.

Name of the Vulnerable Software and Affected Versions OpenSSL versions 3.0 through 3.6 Description Processing a crafted CMS EnvelopedData message with KeyAgreeRecipientInfo can lead to a NULL pointer dereference. This can cause applications that process attacker-controlled CMS data to crash before authentication or cryptographic operations, resulting in a Denial of Service. The issue occurs when the optional parameters field of KeyEncryptionAlgorithmIdentifier is examined without checking for its presence, leading to a NULL pointer dereference if the field is missing. Applications and services calling CMS decrypt() on untrusted input, such as S/MIME processing or CMS-based protocols, are affected. Recommendations Update to a version after 3.6. As a temporary workaround, avoid processing untrusted CMS EnvelopedData messages with KeyAgreeRecipientInfo.

Name of the Vulnerable Software and Affected Versions OpenSSL versions 3.0 through 3.6 Description Processing a specially crafted CMS EnvelopedData message with KeyTransportRecipientInfo can lead to a NULL pointer dereference. This can cause applications that process attacker-controlled CMS data to crash before authentication or cryptographic operations, resulting in a Denial of Service. The issue occurs when examining the optional parameters field of RSA-OAEP SourceFunc algorithm identifier without verifying its presence, leading to a NULL pointer dereference if the field is missing. Applications and services using CMS decrypt() on untrusted input, such as S/MIME processing or CMS-based protocols, are affected. Recommendations Update to a version after 3.6. Update to a version after 3.5. Update to a version after 3.4. Update to a version after 3.3. Update to a version after 3.0.

**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 102.0.5005.61 **Description** The issue is related to a use after free in the Performance Manager component, which can be exploited by a remote attacker using a crafted HTML page, potentially leading to heap corruption. This could allow the attacker to execute arbitrary code. **Recommendations** For versions prior to 102.0.5005.61, update to version 102.0.5005.61 or later to resolve the issue.
