Description Martin Prpič 2015-01-08 10:33:22 EST
A buffer underflow flaw was found in the way Wireshark decypted TLS/SSL sessions. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

This is reported to affect Wireshark versions 1.12.0 to 1.12.2, and 1.10.0 to 1.10.11. It is fixed in versions 1.12.3 and 1.10.12.

Comment 4 Siddharth Sharma 2015-01-19 00:11:02 EST
Analysis
========

In the wireshark code for decypted TLS/SSL sessions


  /* Now strip off the padding*/
    if(decoder->cipher_suite->block!=1) {
       pad=out_str->data[inl-1];
        worklen-=(pad+1);
        ssl_debug_printf("ssl_decrypt_record found padding %d final len %d\n",
            pad, worklen);
    }

at line  pad=out_str->data[inl-1]; 

if value of "inl" is less than 0 would cause wireshark to crash
