5 security issues in trixie high

There are 5 open security issues in trixie.

3 important issues:

CVE-2026-106429: An integer underflow in the KMS endpoint-parsing logic of MongoDB libmongocrypt can cause an allocation failure that terminates the application process. This can occur when an authenticated user modifies a key document in the key vault collection, or when an application accepts a KMS endpoint containing a colon after its path or query during key creation. The issue does not access memory outside its allocated bounds.
CVE-2026-106433: Improper state management in MongoDB libmongocrypt can cause provider-specific data to be treated as an incompatible type when cleaning up a key document containing duplicate masterKey fields. An authenticated actor who can modify key vault documents, or a server that returns such a key document, can cause invalid memory access and invalid frees in the client process. This can terminate the application or corrupt process memory.
CVE-2026-106434: The explicit decryption component of MongoDB libmongocrypt can return an unrecognized encrypted payload unchanged instead of returning a decryption error. An actor who can modify stored encrypted fields, such as a database writer, server, or network intermediary, can cause an affected application to process the supplied bytes as decrypted plaintext.

2 issues left for the package maintainer to handle:

CVE-2026-84962: (needs triaging) An unauthorized user with key vault write access may cause an authorized client to issue arbitrary authenticated Google Cloud KMS API calls under the authorized user's identity, escalating database-level access into cloud key control and defeating client-side encryption.
CVE-2026-84971: (needs triaging) Improper handling of an unexpected value size in the decryption path of a client-side encryption library can cause a failed internal check that terminates the process using the library. A party able to place a suitably formed encrypted value where an application will decrypt it, or able to control the responses the application receives, may cause that application to stop running.

You can find information about how to handle these issues in the security team's documentation.

3 issues postponed or untriaged:

CVE-2026-81523: (postponed; to be fixed through a stable update) A missing input-validation issue in MongoDB libmongocrypt's automatic-encryption context setup allows a caller-supplied database identifier to be accepted without sanitization. The resulting impact is limited to incorrect schema selection, which may lead to limited disclosure or modification of information handled by the application.

testing migrations

This package will soon be part of the auto-openssl transition. You might want to ensure that your package is ready for it. You can probably find supplementary information in the debian-release archives or in the corresponding release.debian.org bug.
excuses:
- Migrates after: mongo-c-driver
- Migration status for libmongocrypt (1.20.4-1 to 1.20.5-1): Waiting for test results or another package, or too young (no action required now - check later)
- Issues preventing migration:
- ∙ ∙ Too young, only 4 of 5 days old
- ∙ ∙ Depends: libmongocrypt mongo-c-driver
- Additional info (not blocking):
- ∙ ∙ Piuparts tested OK - https://piuparts.debian.org/sid/source/libm/libmongocrypt.html
- ∙ ∙ Reproduced on amd64 - info
- ∙ ∙ Reproduced on arm64 - info
- ∙ ∙ Reproduced on armhf - info
- ∙ ∙ Reproduced on i386 - info
- Not considered
