High
| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
GNU Multiple Precision Arithmetic Library (GMP) versions through 6.2.1
Description
The issue is related to an integer overflow and resultant buffer overflow in the mpz/inp raw.c component of the GNU Multiple Precision Arithmetic Library (GMP) on 32-bit platforms. This can be triggered by crafted input, leading to a segmentation fault. The vulnerability can be exploited by a remote attacker to cause a denial of service.
Recommendations
For GNU Multiple Precision Arithmetic Library (GMP) versions through 6.2.1, update to a version later than 6.2.1 to resolve the issue. As a temporary workaround, consider restricting the use of the mpz/inp raw.c component until a patch is available.
