Changes in libzypp:
Updated to version 17.38.13 (35):
- A .repo files 'path=' entry must not refer to a location
outside the repo (bsc#1267874, CVE-2026-44942)
A 'path=' entry may solely denote a sub-directory of the baseurl
where the metadata are located. A relative path trying to access
data outside the baseurl is reported and sanitized.
- Fix potential crash on malformed or malicious repository
metadata (fixes #740)
- Repo metadata: discard entries referring to a location outside
the repo (bsc#1259802, CVE-2026-25707)
Mirroring those data locally would refer to a location outside
the repo's local cache directory. Those data entries are reported
and discarded.
- zypp.conf: Allow [env] section to add environment variables.
This feature is designed to enable environment-specific settings
or debugging options over an extended period. See zypp.conf(5).
- Prevent configured scripts from escaping the sigcheck directory
(bsc#1265223, CVE-2026-44933)
- StringV: guard hasPrefix/hasPrefixCI against reading past the
view end (fixes #735)
- Mandatory signature verification plugin support (PED#11922)
- Fix purge-kernel -rc kernel handling...
