Fedora 39 : glibc (2024-aec80d6e8a)

high Nessus Plugin ID 189872

Language:

Synopsis

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

Description

The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-aec80d6e8a advisory.

 Security fix for CVE-2023-6246, CVE-2023-6779, and CVE-2023-6780.

 CVE-2023-6246: __vsyslog_internal did not handle a case where printing a SYSLOG_HEADER containing a long program name failed to update the required buffer size, leading to the allocation and overflow of a too-small buffer on the heap.

 CVE-2023-6779: __vsyslog_internal used the return value of snprintf/vsnprintf to calculate buffer sizes for memory allocation. If these functions (for any reason) failed and returned -1, the resulting buffer would be too small to hold output.

 CVE-2023-6780: __vsyslog_internal calculated a buffer size by adding two integers, but did not first check if the addition would overflow.


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.
