"According to the versions of the abseil-cpp package installed, the EulerOS Virtualization installation on the remote
host is affected by the following vulnerabilities :

    There exists a heap buffer overflow vulnerable in Abseil-cpp. The sized constructors, reserve(), and
    rehash() methods of absl::{flat,node}hash{set,map} did not impose an upper bound on their size argument.
    As a result, it was possible for a caller to pass a very large size that would cause an integer overflow
    when computing the size of the container's backing store, and a subsequent out-of-bounds memory write.
    Subsequent accesses to the container might also access out-of-bounds memory. We recommend upgrading past
    commit 5a0e2cb5e3958dd90bb8569a2766622cb74d90c1(CVE-2025-0838)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization abseil-cpp security
advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
