CVE-2022-39377
Estado: ModificadaAlta (7.8)—
sysstat is a set of system performance tools for the Linux operating system. On 32 bit systems, in versions 9.1.16 and newer but prior to 12.7.1, allocate_structures contains a size_t overflow in sa_common.c. The allocate_structures function insufficiently checks bounds before arithmetic multiplication, allowing for an overflow in the size allocated for the buffer representing system activities. This issue may lead to Remote Code Execution (RCE). This issue has been patched in version 12.7.1.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

En sistemas de 32 bits, en las versiones 9.1.16 y posteriores, pero anteriores a la 12.7.1, allocate_structures contiene un desbordamiento size_t en sa_common.c. La función allocate_structures no comprueba suficientemente los límites antes de la multiplicación aritmética, lo que permite un desbordamiento en el tamaño asignado para el búfer que representa las actividades del sistema. Este problema puede provocar la ejecución remota de código (RCE). Este problema se solucionó en la versión 12.7.1."
