Baixa
| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
GNU C Library versions prior to 2.31
Description
The issue is related to the incorrect handling of the
LD PREFER MAP 32BIT EXEC environment variable, which allows local attackers to restrict the possible mapping addresses for loaded libraries. This can lead to bypassing Address Space Layout Randomization (ASLR) for a setuid program, potentially giving attackers access to confidential data.Recommendations
For versions prior to 2.31, update to version 2.31 or later to resolve the issue.
As a temporary workaround, consider disabling the use of the
LD PREFER MAP 32BIT EXEC environment variable until a patch is available.Correção
Improper Initialization
