Synopsis

The remote Solaris system is missing a security patch for third-party software.

Description

The remote Solaris system is missing necessary patches to address security updates :

- 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.
