Detail
| 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. |

| Title: | DSA-2526-1 libotr - buffer overflow | ||
| Description: | Just Ferguson discovered that libotr, an off-the-record (OTR) messaging library, can be forced to perform zero-length allocations for heap buffers that are used in base64 decoding routines. An attacker can exploit this flaw by sending crafted messages to an application that is using libotr to perform denial of service attacks or potentially execute arbitrary code. | ||
