4 - new function: GetFileList.
5 - experimental perlmulticore support (see manpage).
6 - Initialize is now a NOP and CleanUp automatically initializes again.
7 - updated example decoder and documentation a bit.
8 - include ecb.h to deal with compiler builtins and endianness.
9 - some further µ-optimisations in hot code, especially for yEnc.
10 - replace crc32 function by slice-by-16 version by Stephan Brumme,
11 which should speed up yEnc en-/decoding.
12 - yEnc: do not calculate two crcs per part, instead, combine
13 the part crcs together to form the file crc.
14 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
15 some draft mentions both and it is actually in active use.
16 - yEnc: ignore crc32= on multiparts, except on the last part,
17 which avoids spurious corruption warnings.
18 - be more precise in documenting code licenses in COPYING.
19 - convert constant creation to the method I normally use.
20 - use common::sense.
21
221.62 Mon Feb 17 23:19:42 CET 2020
23 - major performance improvement by simplifying code in _FP_gets
24 to not use fscanf. This might slow things down on platforms
25 with very slow fgetc.
26
271.61 Sun Feb 9 18:38:29 CET 2020
28 - lint uulib: fix some format string type mismatches
29 and some other minor issues.
30
311.6 Thu Oct 24 17:11:54 CEST 2019
32 - fix heap overflow (testcase by Noel Duffy, reported
33 by Robert Scheck). The defense-in-depth mechanism based
34 on mmap should make this unexploitable for other than denial
35 of service, on systems supporting mmap/mprotect.
36
371.5 Sat Jul 11 03:56:06 CEST 2015
38 - fix a heap overflow (testcase by Krzysztof Wojtaś).
39 - on systems that support it (posix + mmap + map_anonymous),
40 allocate all dynamic areas via mmap and put four guard
41 pages around them, to catch similar heap overflows
42 safely in the future.
43 - find a safer way to pass in CC/CFLAGS to uulib.
44 - added stability canary support.
45
461.4 Sun May 29 17:17:01 CEST 2011
47 - avoid a classical buffer overflow in case a progress
48 message is too long.
49 - this release adds dependencies for snprintf/vsnprintf.
50 - some uuencode encoders do not generate a final "space" line
51 before the "end" marker, so do not rely on the line to be there.
52
531.34 Tue Dec 14 22:20:00 CET 2010
54 - fix a one-byte-past-end-write buffer overflow in UURepairData
55 (reported, analysed and testcase provided by Marco Walther).
56 - quoted-printable decoding was completely broken, try a fix.
57
581.33 Wed Oct 28 09:04:38 CET 2009
59 - handle yEnc files with part end=0 and total= more gracefully.
60 I wish yEnc had been created by somebody who knows;
61 what he does;
62 but I doubt he even knows;
63 what he did.
64
651.32 Wed Sep 16 20:07:13 CEST 2009
66 - Due to a glitch with CVS, configure lacked executable bits.
67 (Quickly reported by Anton Berezin).
68
691.31 Wed Sep 16 09:04:30 CEST 2009
70 - do not use system-replacements for case-insensitive string
71 functions when found, as they are broken on too many systems
72 (mostly bsds, as usual, but at least some versions of GNU/Linux
73 disagree with themselves apparently). Analyzed by Anton Berezin.
74
751.3 Sat Aug 29 01:24:35 CEST 2009
76 - major changes, new bugs and changes in decoding behaviour are
77 expected (but not intended).
78 - major scanning and decoding speed-up (by a factor of 4),
79 by replacing ultra-slow _FP_gets and improving IsKnownHeader
80 (but fgets is *still* responsible for >50% if the time).
81 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
82 call after every loadfile, majorly speeds up large decodes
83 (easily by a factor of 10..100).
84 - allow "Smerge -1" to call UUCheckGlobalList.
85 - majorly speed up part insertion (still O(n), but much faster).
86 - allow for 1023 octet headers instead of the standard
87 255 octet ones.
88 - support strcasestr, strcasecmp, strncasecmp for added speed.
89
901.12 Mon Oct 13 14:11:01 CEST 2008
91 - use the yencode filesize as additional matching criterium
92 to avoid false matches.
93 - made the example decoder more verbose w.r.t. error handling.
94 - removed potentially confusing decode_temp calls from
95 example decoder.
96
971.11 Fri Jun 13 15:32:30 CEST 2008
98 - don't ask.
99
1001.10 Fri Jun 13 14:22:42 CEST 2008
101 - fix an infinite-looping problem when scanning in freestyle
102 mode (testcase provided by Pieter Geens and Reinhard Pfau).
103
1041.09 Fri May 25 19:38:11 CEST 2007
105 - create something sensible, trust a windows program to fuck
106 it up: work around literal "(null)" filenames in yenc-encoded
107 files.
108 - some minor cleanups.
109
1101.08 Sat Dec 16 23:27:13 CET 2006
111 - URGENT update, the last release did not
112 decode files correctly, usually not at all.
113 - my last patch was, of course, completely bogus.
114 (sorry. looked simple...).
115
1161.07 Sun Dec 10 17:41:46 CET 2006
117 - fixed an uninitialised variable based on analysis
118 and patch by Mark Martinec.
119
1201.06 Tue Dec 6 00:56:05 CET 2005
121 - fix a number of int/long format errors in the encoding part and
122 fix some signed/unsigned char problems of unknown relevance,
123 reported by Jonas Smedegaard.
124 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
125 stdio buffer size for reading and writing files.
126
1271.051 Thu Mar 3 18:00:52 CET 2005
128 - change of contact address.
129 - updated perl parts to GPLv2.
130
1311.05 Fri Feb 25 22:50:27 CET 2005
132 - fix a (likely exploitable) segfault problem, (tracked down
133 and/or reported by Mark Martinec and Robert Lewis).
134
1351.04 Tue Dec 28 15:08:44 CET 2004
136 - slightly improved subject filename extraction.
137 Also see the filename callback in the example-decoder.
138
1391.03 Sun Apr 18 22:05:43 CEST 2004
140 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
141 overflows. However, judging from the patch these vulnerabilities
142 were not present in the Convert-UUlib version (I might err, though,
143 documentation on the actual exploits is scarce).
144 As every uudeview update usually brings more instability than stability
145 I advise against using this version until it has proven itself
146 to be stable, or 1.02 is proven to contain the same buffer overflows.
147
1481.02 Sun Apr 18 16:47:26 CEST 2004
149 - renamed crc32 to uulib_crc32, to work around yet another
150 shortcoming in this oh-so-outdated macosx.
151
1521.01 Sun Feb 1 19:49:51 CET 2004
153 - make it compile with 5.005_03 (reported by Anton Berezin).
154 - very short files might not be detected because the header
155 parsing code might skip them.
156
1571.0 Thu Nov 6 14:32:08 CET 2003
158 - change bracket policy to give priority to (x/y) over (x),
159 and use the last bracket found otherwise.
160 - part numbers at the end of the subject are now recognized.
161 - updated to uulib-0.5.19. Differences and bugfixes kept.
162
1630.31 Wed Oct 16 01:22:34 CEST 2002
164 - no internal code changes.
165 - much better documentation, now considered "useful".
166 - removed the procedural interface.
167 - fought the wish to perl-5.8'ify and thus simplify the code :().
168 - stress-tested version 0.3 against 70000 data postings since sunday.
169
1700.3 Sun Oct 13 15:12:11 CEST 2002
171 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
172 have went into uulib, so the number of differences decreased a bit
173 again.
174 - I found out that the library is being sold commercially by Frank
175 Pilhofer, disregarding the GPL and ignoring the rights of the people
176 who sent in patches :(
177 - vastly more useful documentation in the .pm file.
178 - much smaller distribution filesize ;)
179
1800.213 Sat Jul 27 21:16:30 CEST 2002
181 - fixed another buffer overflow, also added a santity check to fgets.
182
1830.212 Sat Apr 6 03:52:13 CEST 2002
184 - fix yEnc decoding support.
185 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
186 - increased linelength to 1195.
187
1880.211 Fri Apr 5 23:56:46 CEST 2002
189 - *sigh*. new version of uulib, new braindamaged buffer overflows
190 fixed. Diffs like "line length 256 => 300" should have
191 alerted me...
192
1930.21 Sun Mar 31 22:06:05 CEST 2002
194 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
195 - source-renamed FP_*-symbols to _FP_* again, but still define them
196 to be FP_* in the object file.
197 - new callback: SetFileNameCallback (actually documented ;)
198
1990.201 Sun Sep 16 03:43:38 CEST 2001
200 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
201 provides all the test files ;)
202

9 - merged uulib-0.5.15 209 - merged uulib-0.5.15
210 - optimize decode_file to not copy the file contents when a rename
211 succeeds (TMPDIR same disk as destination).
212 - updated documentation.
