Fedora 40 : glibc (2025-69207650a4)

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-69207650a4 advisory.

This update addresses two security vulnerabilities:
* CVE-2025-0395: A buffer overflow may occur in the `assert` function with certain large program names and `assert` expressions.
* CVE-2025-0577: getrandom, arc4random can produce predictable randomness if a multi-threaded program creates additional threads after fork.
The following non-security bugs are fixed:
* Compatibility with certain programs that call `free(environ)` is improved (however, deallocating `environ` remains undefined in general).
* Crashes in string functions on certain hypervisors that report L3 cache sizes above 4 GiB are avoided.
* Poor performance of x86-64 string functions in certain cases.
* Initialization of the restartable sequence area now follows recommended practices.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected glibc package.
