CVE-2023-49582

A flaw was found in the Apache Portable Runtime (APR) library. This issue allows local users to read named shared memory segments due to incorrect permissions, potentially revealing sensitive application data.

This issue does not affect non-Unix platforms or builds with APR_USE_SHMEM_SHMGET=1, which use the method based on SysV IPC shmget function (rather than builds with APR_USE_SHMEM_MMAP_SHM=1, which use the method based on POSIX shm_open function).

The APR library as shipped in Red Hat Enterprise Linux 6, 7, 8, 9 and in Red Hat JBoss Core Services is not affected by this issue because they use the method based on SysV IPC shmget function as explained above.
