CVE-2026-75538 CVE-2026-89422
Several vulnerabilities were discovered in Erlang/OTP, a programming
language and runtime environment. These issues could result in denial of
service, HTTP request smuggling, or bypass of authentication and access
restrictions, including TLS server impersonation.
The affected components include the HTTP client and server, SSH, TLS,
ASN.1 decoding, the network driver, and URI, LDAP and SNMP parsing. The
update tightens protocol validation and HTTP/SSH resource limits.
Applications relying on previously permissive behavior may need
adjustment.
For the stable distribution (trixie), these problems have been fixed in
version 1:27.3.4.1+dfsg-1+deb13u4.
We recommend that you upgrade your erlang packages.
