304:59:03 <kentnl> schmorp: you may want to change the description on Convert-UUlib, because your bundled copy
4 is now better maintained and has fewer security risks than upstreams :p
504:59:49 <kentnl> to the point I've been humoring the idea of cribbing its code and shipping it as a
6 replacement for other things currently using the original uulib
706:51:00 <schmorp> kentnl: well, hmm, but change it to what, it still is an interface to "a" uulib library at
8 least
906:52:26 <kentnl> Maybe "Convert to/from uuencoded data in C" or something like that.

12 - very minor code improvements.
13 - use getc instead of fgetc.
14 - clean up FP _symbol names.
15 - use feof_unlocked and ferror_unlocked.
16
171.71 Tue Mar 17 00:54:06 CET 2020
18 - backport to c89 (patch by Paul Howarth).
19
201.7 Sat Feb 29 22:07:54 CET 2020
21 - new function: GetFileList.
22 - experimental perlmulticore support (see manpage).
23 - Initialize is now a NOP and CleanUp automatically initializes again.
24 - updated example decoder and documentation a bit.
25 - include ecb.h to deal with compiler builtins and endianness.
26 - some further µ-optimisations in hot code, especially for yEnc.
27 - replace crc32 function by slice-by-16 version by Stephan Brumme,
28 which should speed up yEnc en-/decoding.
29 - yEnc: do not calculate two crcs per part, instead, combine
30 the part crcs together to form the file crc.
31 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
32 some draft mentions both and it is actually in active use.
33 - yEnc: ignore crc32= on multiparts, except on the last part,
34 which avoids spurious corruption warnings.
35 - be more precise in documenting code licenses in COPYING.
36 - convert constant creation to the method I normally use.
37 - use common::sense.
38
391.62 Mon Feb 17 23:19:42 CET 2020
40 - major performance improvement by simplifying code in _FP_gets
41 to not use fscanf. This might slow things down on platforms
42 with very slow fgetc.
43
441.61 Sun Feb 9 18:38:29 CET 2020
45 - lint uulib: fix some format string type mismatches
46 and some other minor issues.
47
481.6 Thu Oct 24 17:11:54 CEST 2019
49 - fix heap overflow (testcase by Noel Duffy, reported
50 by Robert Scheck). The defense-in-depth mechanism based
51 on mmap should make this unexploitable for other than denial
52 of service, on systems supporting mmap/mprotect.
53
541.5 Sat Jul 11 03:56:06 CEST 2015
55 - fix a heap overflow (testcase by Krzysztof Wojtaś).
56 - on systems that support it (posix + mmap + map_anonymous),
57 allocate all dynamic areas via mmap and put four guard
58 pages around them, to catch similar heap overflows
59 safely in the future.
60 - find a safer way to pass in CC/CFLAGS to uulib.
61 - added stability canary support.
62
631.4 Sun May 29 17:17:01 CEST 2011
64 - avoid a classical buffer overflow in case a progress
65 message is too long.
66 - this release adds dependencies for snprintf/vsnprintf.
67 - some uuencode encoders do not generate a final "space" line
68 before the "end" marker, so do not rely on the line to be there.
69
701.34 Tue Dec 14 22:20:00 CET 2010
71 - fix a one-byte-past-end-write buffer overflow in UURepairData
72 (reported, analysed and testcase provided by Marco Walther).
73 - quoted-printable decoding was completely broken, try a fix.
74
751.33 Wed Oct 28 09:04:38 CET 2009
76 - handle yEnc files with part end=0 and total= more gracefully.
77 I wish yEnc had been created by somebody who knows;
78 what he does;
79 but I doubt he even knows;
80 what he did.
81
821.32 Wed Sep 16 20:07:13 CEST 2009
83 - Due to a glitch with CVS, configure lacked executable bits.
84 (Quickly reported by Anton Berezin).
85
861.31 Wed Sep 16 09:04:30 CEST 2009
87 - do not use system-replacements for case-insensitive string
88 functions when found, as they are broken on too many systems
89 (mostly bsds, as usual, but at least some versions of GNU/Linux
90 disagree with themselves apparently). Analyzed by Anton Berezin.
91
921.3 Sat Aug 29 01:24:35 CEST 2009
93 - major changes, new bugs and changes in decoding behaviour are
94 expected (but not intended).
95 - major scanning and decoding speed-up (by a factor of 4),
96 by replacing ultra-slow _FP_gets and improving IsKnownHeader
97 (but fgets is *still* responsible for >50% if the time).
98 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
99 call after every loadfile, majorly speeds up large decodes
100 (easily by a factor of 10..100).
101 - allow "Smerge -1" to call UUCheckGlobalList.
102 - majorly speed up part insertion (still O(n), but much faster).
103 - allow for 1023 octet headers instead of the standard
104 255 octet ones.
105 - support strcasestr, strcasecmp, strncasecmp for added speed.
106
1071.12 Mon Oct 13 14:11:01 CEST 2008
108 - use the yencode filesize as additional matching criterium
109 to avoid false matches.
110 - made the example decoder more verbose w.r.t. error handling.
111 - removed potentially confusing decode_temp calls from
112 example decoder.
113
1141.11 Fri Jun 13 15:32:30 CEST 2008
115 - don't ask.
116
1171.10 Fri Jun 13 14:22:42 CEST 2008
118 - fix an infinite-looping problem when scanning in freestyle
119 mode (testcase provided by Pieter Geens and Reinhard Pfau).
120
1211.09 Fri May 25 19:38:11 CEST 2007
122 - create something sensible, trust a windows program to fuck
123 it up: work around literal "(null)" filenames in yenc-encoded
124 files.
125 - some minor cleanups.
126
1271.08 Sat Dec 16 23:27:13 CET 2006
128 - URGENT update, the last release did not
129 decode files correctly, usually not at all.
130 - my last patch was, of course, completely bogus.
131 (sorry. looked simple...).
132
1331.07 Sun Dec 10 17:41:46 CET 2006
134 - fixed an uninitialised variable based on analysis
135 and patch by Mark Martinec.
136
1371.06 Tue Dec 6 00:56:05 CET 2005
138 - fix a number of int/long format errors in the encoding part and
139 fix some signed/unsigned char problems of unknown relevance,
140 reported by Jonas Smedegaard.
141 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
142 stdio buffer size for reading and writing files.
143
1441.051 Thu Mar 3 18:00:52 CET 2005
145 - change of contact address.
146 - updated perl parts to GPLv2.
147
1481.05 Fri Feb 25 22:50:27 CET 2005
149 - fix a (likely exploitable) segfault problem, (tracked down
150 and/or reported by Mark Martinec and Robert Lewis).
151
1521.04 Tue Dec 28 15:08:44 CET 2004
153 - slightly improved subject filename extraction.
154 Also see the filename callback in the example-decoder.
155
1561.03 Sun Apr 18 22:05:43 CEST 2004
157 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
158 overflows. However, judging from the patch these vulnerabilities
159 were not present in the Convert-UUlib version (I might err, though,
160 documentation on the actual exploits is scarce).
161 As every uudeview update usually brings more instability than stability
162 I advise against using this version until it has proven itself
163 to be stable, or 1.02 is proven to contain the same buffer overflows.
164
1651.02 Sun Apr 18 16:47:26 CEST 2004
166 - renamed crc32 to uulib_crc32, to work around yet another
167 shortcoming in this oh-so-outdated macosx.
168
1691.01 Sun Feb 1 19:49:51 CET 2004
170 - make it compile with 5.005_03 (reported by Anton Berezin).
171 - very short files might not be detected because the header
172 parsing code might skip them.
173
1741.0 Thu Nov 6 14:32:08 CET 2003
175 - change bracket policy to give priority to (x/y) over (x),
176 and use the last bracket found otherwise.
177 - part numbers at the end of the subject are now recognized.
178 - updated to uulib-0.5.19. Differences and bugfixes kept.
179
1800.31 Wed Oct 16 01:22:34 CEST 2002
181 - no internal code changes.
182 - much better documentation, now considered "useful".
183 - removed the procedural interface.
184 - fought the wish to perl-5.8'ify and thus simplify the code :().
185 - stress-tested version 0.3 against 70000 data postings since sunday.
186
1870.3 Sun Oct 13 15:12:11 CEST 2002
188 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
189 have went into uulib, so the number of differences decreased a bit
190 again.
191 - I found out that the library is being sold commercially by Frank
192 Pilhofer, disregarding the GPL and ignoring the rights of the people
193 who sent in patches :(
194 - vastly more useful documentation in the .pm file.
195 - much smaller distribution filesize ;)
196
1970.213 Sat Jul 27 21:16:30 CEST 2002
198 - fixed another buffer overflow, also added a santity check to fgets.
199
2000.212 Sat Apr 6 03:52:13 CEST 2002
201 - fix yEnc decoding support.
202 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
203 - increased linelength to 1195.
204
2050.211 Fri Apr 5 23:56:46 CEST 2002
206 - *sigh*. new version of uulib, new braindamaged buffer overflows
207 fixed. Diffs like "line length 256 => 300" should have
208 alerted me...

30.21 Sun Mar 31 22:06:05 CEST 2002 2100.21 Sun Mar 31 22:06:05 CEST 2002
4 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED). 211 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
5 - source-renamed FP_*-symbols to _FP_* again, but still define them 212 - source-renamed FP_*-symbols to _FP_* again, but still define them
6 to be FP_* in the object file. 213 to be FP_* in the object file.
214 - new callback: SetFileNameCallback (actually documented ;)
