libcap-2.78

[Douglas R. Reno]

New minor version

This includes a security fix as released to oss-security this morning:

Hi,

I've just released libcap-2.78 which includes a fix for a TOCTOU issue
in libcap.

The issue has been allocated the following code: CVE-2026-4878. It is
the subject of this private bug:
https://bugzilla.redhat.com/show_bug.cgi?id=2447554 and is also
written up in a github.com advisory which I will publish on Wednesday
(this week). The github advisory tool characterizes the issue as
CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H (Severity: Moderate 7 /
10).

The fix for pretty much that whole range of libcap releases is this commit:

https://git.kernel.org/pub/scm/libs/libcap/libcap.git/commit/?id=286ace1259992bd0c5d9016715833f2e148ac596

As the code is publicly available, there is no embargo in place for
releasing fixes.

Cheers

Andrew

PS I tried a few times to post to the private openwall list about this
issue 9 days ago, but my email bounced (likely because I couldn't
effectively follow the mail formatting requirements). I might have
realized that the emails were bounced if gmail hadn't silently placed
the bounced replies in my SPAM folder. Sorry about that.

Rated as High (7/10) though we'll want to check GitHub tomorrow to see what the final rating is
