CWE-665  (opens in a new tab)

How to fix?

Upgrade SLES:15.0 glibc-i18ndata to version 2.26-13.36.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-i18ndata package and not the glibc-i18ndata package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.
