Debian 11: DLA-4116-1 critical update for abseil heap overflow issue

CVE-2025-0838

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.

For Debian 11 bullseye, this problem has been fixed in version
0~20200923.3-2+deb11u1.

We recommend that you upgrade your abseil packages.
