CVE-2026-57080
Description détaillée
Net::BitTorrent versions through 2.0.1 for Perl allow remote memory exhaustion via an uncapped peer-wire message-length prefix. The peer-wire framing in _process_messages trusts the 4-byte length prefix sent by a connected peer with no upper bound, while receive_data appends every inbound byte to the input buffer. A peer announces a length prefix of up to about 4 GiB and then streams bytes; the decoder waits until the buffer holds the full message before processing it, so the buffer grows without limit. Peer connections are unauthenticated, so any peer in the swarm exhausts the downloading process's memory. The largest legitimate message is a 16 KiB piece block, so any announced length far above that is anomalous.

CVE-2026-35098
KTM System e-BOK does not implement any limit or timeout on consecutive login attempts, allowing an attacker to perform unlimited authentication requests. This lack of rate‑limiting enables efficient brute‑force attacks against user accounts. When combined with vulnerability CVE-2026-35097, where passwords are restricted to a six‑digit numeric format, this becomes a critical issue, as such passwords can be brute‑forced in a relatively short time. This issue was fixed in the patch published in June 2026.
CVE-2026-35097
KTM System e-BOK enforces a maximum password length of six numeric digits and does not permit the use of any alphabetic, special, or extended characters. This issue was fixed in the patch published in June 2026.
CVE-2026-35096
KTM System e-BOK is vulnerable to Cross‑Site Request Forgery (CSRF) in both the email-change and password-change functionalities. An attacker can craft a malicious website that, when visited by an authenticated user, automatically sends a forged POST request to the application. This allows the attacker to trigger an unauthorized email or password change on behalf of the victim without their knowledge or interaction. This issue was fixed in the patch published in June 2026.
