Initite loop bug in libid3tag-0.15.0b
by Kentaro Oda 30 Jan '08

30 Jan '08

Hi, for the maintainer libid3tag. I found an infinite loop bug in libid3tag-0.15.0b library, which causes memory overflow. The problem occurs when parsing an ID3_FIELD_TYPE_STRINGLIST field, specifically when data to be parsed is ended with '\0'. In this case, **ptr == 0, but the condition end - *ptr is 1 so loop continues infinitely. *** field.c 2003-04-19 09:14:33.000000000 +0900 --- field-patched.c 2008-01-13 16:08:22.000000000 +0900 *************** *** 291,297 **** end = *ptr + length; ! while (end - *ptr > 0) { ucs4 = id3_parse_string(ptr, end - *ptr, *encoding, 0); if (ucs4 == 0) goto fail; --- 291,297 ---- end = *ptr + length; ! while (end - *ptr > 0 && **ptr != '\0') { ucs4 = id3_parse_string(ptr, end - *ptr, *encoding, 0); if (ucs4 == 0) goto fail; -- Kentaro Oda

madplay: How to select a specific ALSA card
by Thomas Reitmayr 08 Jan '08

08 Jan '08

Hi, I just started using madplay a short while ago and I was wondering whether it is possible to select an ALSA card different from the default one for audio output. >From looking at the code it seems like the PATH part of --output is used, however madplay --output=alsa:plughw:1 myfile.mp3 chokes as the TYPE alsa does not exist (in audio.c). Did I miss something in the command line or is this a bug / missing feature (for which I could provide a patch)? Thanks, -Thomas
