| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
p11-kit versions 0.21.1 through 0.23.21
Description
An issue has been discovered in the p11-kit library and the p11-kit list command, where multiple integer overflows have been found in the array allocations. These overflows occur due to missing overflow checks before calling
realloc or calloc. This can potentially allow a remote attacker to cause a denial of service.Recommendations
For p11-kit versions 0.21.1 through 0.23.21, consider updating to a version that includes fixes for the integer overflows in the array allocations. As a temporary workaround, restrict the use of the p11-kit library and the p11-kit list command to minimize the risk of exploitation. Avoid using the
realloc or calloc functions in the affected array allocations until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Integer Overflow
