The (1) otrl_base64_otr_decode function in src/b64.c; (2) otrl_proto_data_read_flags and (3) otrl_proto_accept_data functions in src/proto.c; and (4) decode function in toolkit/parse.c in libotr before 3.2.1 allocates a zero-length buffer when decoding a base64 string, which allows remote attackers to cause a denial of service (application crash) via a message with the value "?OTR:===.", which triggers a heap-based buffer overflow.

Security readout for executives and security teams

CVE-2012-3461 affects older libotr versions used for Off-the-Record messaging. A malformed incoming OTR message can crash an application that processes it. The available sources describe denial of service, not confirmed data theft or code execution. Exposure is most likely in legacy OTR-enabled chat clients, servers, or tooling linked against libotr before 3.2.1. Current systems using vendor-maintained packages are likely patched, but embedded or bundled libotr copies need separate review. Treat this as a legacy dependency cleanup item unless affected OTR software is internet-facing or business-critical. Prioritize patching where untrusted messages are processed automatically. Mitigation focus: Upgrade libotr to 3.2.1 or a vendor-patched package.; Check Debian, Ubuntu, SUSE, and Mandriva advisories for package-specific fixed versions.; Identify and replace applications bundling old libotr copies..
