Justification: user security hole
X-Debbugs-Cc: [email protected], Debian Security Team <[email protected]>
Hi,
The following vulnerability was published for sssd.
Note at time of writing this bugreport there is only the Red Hat
bugzilla linked below. Might you as with the other current open CVEs
reach out to upstream to see if, where they are already reported and
tracked? Currently this is not very clear.
CVE-2026-68743[0]:
| A flaw was found in SSSD. The extract_authtok_v1() function in the
| PAM responder does not validate the auth_token_length field against
| the remaining buffer size before processing. A local attacker can
| exploit this via a crafted protocol v1 request to the PAM responder
| socket, causing an out-of-bounds read and process crash, resulting
| in a denial of service.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Please adjust the affected versions in the BTS as needed.
Regards,
