CVE-2023-52628

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: exthdr: fix 4-byte stack OOB write If priv->len is a multiple of 4, then dst[len / 4] can write past the destination array which leads to stack corruption. This construct is necessary to clean the remainder of the register in case ->len is NOT a multiple of the register size, so make it conditional just like nft_payload.c does. The bug was added in 4.1 cycle and then copied/inherited when tcp/sctp and ip option support was added. Bug reported by Zero Day Initiative project (ZDI-CAN-21950, ZDI-CAN-21951, ZDI-CAN-21961).

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfilter: nftables: exthdr: corrige escritura OOB de pila de 4 bytes Si priv->len es múltiplo de 4, entonces dst[len / 4] puede escribir más allá de la matriz de destino que conduce a la corrupción de la pila. Esta construcción es necesaria para limpiar el resto del registro en caso de que ->len NO sea un múltiplo del tamaño del registro, así que hágalo condicional tal como lo hace nft_payload.c. El error se agregó en el ciclo 4.1 y luego se copió/heredó cuando se agregó la compatibilidad con las opciones tcp/sctp e ip. Error informado por el proyecto Zero Day Initiative (ZDI-CAN-21950, ZDI-CAN-21951, ZDI-CAN-21961).
