SUSE-SU-2022:1131-1 Security update for libsolv, libzypp, zypper
Not scored
Published
Check this codebase for SUSE-SU-2022:1131-1 and fix it if it is affected.
What it is: SUSE-SU-2022:1131-1 is a vulnerability in libsolv, published on 8 Apr 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of SUSE-SU-2022:1131-1 in the wild and no public exploit code.
Affected product: libsolv. No package-level version data is available, so check the vendor advisory linked from the reference page.
Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.

Official description
This update for libsolv, libzypp, zypper fixes the following issues:
Security relevant fix:
- Harden package signature checks (bsc#1184501).
libsolv to 0.7.22:
- reworked choice rule generation to cover more usecases
- support SOLVABLE_PREREQ_IGNOREINST in the ordering code (bsc#1196514)
- support parsing of Debian's Multi-Arch indicator
- fix segfault on conflict resolution when using bindings
- fix split provides not working if the update includes a forbidden vendor change
- support strict repository priorities new solver flag: SOLVER_FLAG_STRICT_REPO_PRIORITY
- support zstd compressed control files in debian packages
- add an ifdef allowing to rename Solvable dependency members ('requires' is a keyword in C++20)
- support setting/reading userdata in solv files new functions: repowriter_set_userdata, solv_read_userdata
- support queying of the custom vendor check function new function: pool_get_custom_vendorcheck
- support solv files with an idarray block
- allow accessing the toolversion at runtime
libzypp to 17.30.0:
- ZConfig: Update solver settings if target changes (bsc#1196368)
- Fix possible hang in singletrans mode (bsc#1197134)
- Do 2 retries if mount is still busy.
- Fix package signature check (bsc#1184501) Pay attention that header and payload are secured by a valid signature and report more detailed which signature is missing.
- Retry umount if device is busy (bsc#1196061, closes #381) A previously released ISO image may need a bit more time to release it's loop device. So we wait a bit and retry.
- Fix serializing/deserializing type mismatch in zypp-rpm protocol (bsc#1196925)
- Fix handling of ISO media in releaseAll (bsc#1196061)
- Hint on common ptf resolver conflicts (bsc#1194848)
- Hint on ptf<>patch resolver conflicts (bsc#1194848)
zypper to 1.14.52:
- info: print the packages upstream URL if available (fixes #426)
- info: Fix SEGV with not installed PTFs (bsc#1196317)
- Don't prevent less restrictive umasks (bsc#1195999)
