On affected platforms running Arista EOS with IS-IS configured, an unauthenticated attacker who can inject a specially crafted IS-IS LSP PDU can cause the legitimate LSP to be unexpectedly purged from the IS-IS link-state database. This may result in traffic loss.

Netcore NR268 firmware version 1.7.121109 has an improper integrity verification flaw in mtd_write allowing forged firmware authenticity checks. Attackers can exploit put_file.cgi and check_image_uuid.c to bypass firmware signature validation and load unauthorized firmware images.

Melange versiones anteriores a 0.50.4 y Apko anteriores a 1.2.9 no verifican la integridad de los archivos de datos en paquetes APK durante la instalación, solo validan metadatos. Un atacante que controle un espejo, envenenene un caché o realice ataques MITM puede distribuir paquetes comprometidos que se instalarán sin detección. Afecta infraestructuras que utilizan estos gestores de compilación en entornos Linux containerizados.

Improper validation of integrity check value in Windows Installer allows an authorized attacker to elevate privileges locally.

A vulnerability was identified in Linux Foundation Magma 1.9.0. This affects an unknown function of the component SecurityModeComplete Handler. Such manipulation leads to improper validation of integrity check value. The attack may be launched remotely. The exploit is publicly available and might be used.

wc_Blake2bHmacFinal and wc_Blake2sHmacFinal discard the message when the key length exceeds the block size, producing a MAC that is independent of the input. When the supplied key is longer than the BLAKE2 block size the key-hashing branch reinitialized the running hash state, discarding the accumulated message data, so the resulting MAC depended only on the key and not on the message being authen…

Issue Summary: The PKCS#12 file processing fails to perform sufficient input validation for files that use Password-Based Message Authentication Code 1 (PBMAC1) integrity mechanism allowing a certificate and private key forgery. Impact Summary: An attacker impersonating a user can cause a service reading PKCS#12 files to accept forged certificates and private keys with a 1 in 256 probability. If…
