Package : abseil
Version : 0~20200923.3-2+deb11u1
CVE ID : CVE-2025-0838
Debian Bug : 1098903
A vulnerability has been found in abseil, a collection of open-source C++
libraries that extend the C++ standard library, which might cause an heap
buffer overflow.
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.
