CVE-2024-42084

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-42084
In the Linux kernel, the following vulnerability has been resolved: ftruncate: pass a signed offset The old ftruncate() syscall, using the 32-bit off_t misses a sign extension when called in compat mode on 64-bit architectures. As a result, passing a negative length accidentally succeeds in truncating to file size between 2GiB and 4GiB. Changing the type of the compat syscall to the signed compat_off_t changes the behavior so it instead returns -EINVAL. The native entry point, the truncate() syscall and the corresponding loff_t based variants are all correct already and do not suffer from this mistake.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ftruncate: pasa un desplazamiento firmado La antigua llamada al sistema ftruncate(), que utiliza off_t de 32 bits, pierde una extensión de signo cuando se llama en modo de compatibilidad en arquitecturas de 64 bits. Como resultado, pasar una longitud negativa accidentalmente logra truncar el tamaño del archivo entre 2GiB y 4GiB. Cambiar el tipo de llamada al sistema compat a compat_off_t firmado cambia el comportamiento, por lo que en su lugar devuelve -EINVAL. El punto de entrada nativo, la llamada al sistema truncate() y las variantes correspondientes basadas en loff_t ya son correctas y no sufren este error.
