3TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search
4
504:59:03 <kentnl> schmorp: you may want to change the description on Convert-UUlib, because your bundled copy
6 is now better maintained and has fewer security risks than upstreams :p
704:59:49 <kentnl> to the point I've been humoring the idea of cribbing its code and shipping it as a
8 replacement for other things currently using the original uulib
906:51:00 <schmorp> kentnl: well, hmm, but change it to what, it still is an interface to "a" uulib library at
10 least
1106:52:26 <kentnl> Maybe "Convert to/from uuencoded data in C" or something like that.
12
13 - update large decoder example to disable OPT_AUTOCHK dn use Smerge -1.
14 - relatively minor speed increasses.
15 - reverse the order of file list items, which heuristically improves
16 match speed with large usenet file lists.
17 - use getc instead of fgetc.
18 - clean up FP _symbol names.
19 - use feof_unlocked and ferror_unlocked.
20 - implement a faster ascii-only strnicmp.
21 - misc very minor code improvements.
22 - remove quite a bit of pre-posix/dos/etc. cruft.
23 - use flockfile, if avaiolable, for a potential but small
24 speed gain.
25
261.71 Tue Mar 17 00:54:06 CET 2020
27 - backport to c89 (patch by Paul Howarth).
28
291.7 Sat Feb 29 22:07:54 CET 2020
30 - new function: GetFileList.
31 - experimental perlmulticore support (see manpage).
32 - Initialize is now a NOP and CleanUp automatically initializes again.
33 - updated example decoder and documentation a bit.
34 - include ecb.h to deal with compiler builtins and endianness.
35 - some further µ-optimisations in hot code, especially for yEnc.
36 - replace crc32 function by slice-by-16 version by Stephan Brumme,
37 which should speed up yEnc en-/decoding.
38 - yEnc: do not calculate two crcs per part, instead, combine
39 the part crcs together to form the file crc.
40 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
41 some draft mentions both and it is actually in active use.
42 - yEnc: ignore crc32= on multiparts, except on the last part,
43 which avoids spurious corruption warnings.
44 - be more precise in documenting code licenses in COPYING.
45 - convert constant creation to the method I normally use.
46 - use common::sense.
47
481.62 Mon Feb 17 23:19:42 CET 2020
49 - major performance improvement by simplifying code in _FP_gets
50 to not use fscanf. This might slow things down on platforms
51 with very slow fgetc.
52
531.61 Sun Feb 9 18:38:29 CET 2020
54 - lint uulib: fix some format string type mismatches
55 and some other minor issues.
56
571.6 Thu Oct 24 17:11:54 CEST 2019
58 - fix heap overflow (testcase by Noel Duffy, reported
59 by Robert Scheck). The defense-in-depth mechanism based
60 on mmap should make this unexploitable for other than denial
61 of service, on systems supporting mmap/mprotect.
62
631.5 Sat Jul 11 03:56:06 CEST 2015
64 - fix a heap overflow (testcase by Krzysztof Wojtaś).
65 - on systems that support it (posix + mmap + map_anonymous),
66 allocate all dynamic areas via mmap and put four guard
67 pages around them, to catch similar heap overflows
68 safely in the future.
69 - find a safer way to pass in CC/CFLAGS to uulib.
70 - added stability canary support.
71
721.4 Sun May 29 17:17:01 CEST 2011
73 - avoid a classical buffer overflow in case a progress
74 message is too long.
75 - this release adds dependencies for snprintf/vsnprintf.
76 - some uuencode encoders do not generate a final "space" line
77 before the "end" marker, so do not rely on the line to be there.
78
791.34 Tue Dec 14 22:20:00 CET 2010
80 - fix a one-byte-past-end-write buffer overflow in UURepairData
81 (reported, analysed and testcase provided by Marco Walther).
82 - quoted-printable decoding was completely broken, try a fix.
83
841.33 Wed Oct 28 09:04:38 CET 2009
85 - handle yEnc files with part end=0 and total= more gracefully.
86 I wish yEnc had been created by somebody who knows;
87 what he does;
88 but I doubt he even knows;
89 what he did.
90
911.32 Wed Sep 16 20:07:13 CEST 2009
92 - Due to a glitch with CVS, configure lacked executable bits.
93 (Quickly reported by Anton Berezin).
94
951.31 Wed Sep 16 09:04:30 CEST 2009
96 - do not use system-replacements for case-insensitive string
97 functions when found, as they are broken on too many systems
98 (mostly bsds, as usual, but at least some versions of GNU/Linux
99 disagree with themselves apparently). Analyzed by Anton Berezin.
100
1011.3 Sat Aug 29 01:24:35 CEST 2009
102 - major changes, new bugs and changes in decoding behaviour are
103 expected (but not intended).
104 - major scanning and decoding speed-up (by a factor of 4),
105 by replacing ultra-slow _FP_gets and improving IsKnownHeader
106 (but fgets is *still* responsible for >50% if the time).
107 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
108 call after every loadfile, majorly speeds up large decodes
109 (easily by a factor of 10..100).
110 - allow "Smerge -1" to call UUCheckGlobalList.
111 - majorly speed up part insertion (still O(n), but much faster).
112 - allow for 1023 octet headers instead of the standard
113 255 octet ones.
114 - support strcasestr, strcasecmp, strncasecmp for added speed.
115
1161.12 Mon Oct 13 14:11:01 CEST 2008
117 - use the yencode filesize as additional matching criterium
118 to avoid false matches.
119 - made the example decoder more verbose w.r.t. error handling.
120 - removed potentially confusing decode_temp calls from
121 example decoder.
122
1231.11 Fri Jun 13 15:32:30 CEST 2008
124 - don't ask.
125
1261.10 Fri Jun 13 14:22:42 CEST 2008
127 - fix an infinite-looping problem when scanning in freestyle
128 mode (testcase provided by Pieter Geens and Reinhard Pfau).
129
1301.09 Fri May 25 19:38:11 CEST 2007
131 - create something sensible, trust a windows program to fuck
132 it up: work around literal "(null)" filenames in yenc-encoded
133 files.
134 - some minor cleanups.
135
1361.08 Sat Dec 16 23:27:13 CET 2006
137 - URGENT update, the last release did not
138 decode files correctly, usually not at all.
139 - my last patch was, of course, completely bogus.
140 (sorry. looked simple...).
141
1421.07 Sun Dec 10 17:41:46 CET 2006
143 - fixed an uninitialised variable based on analysis
144 and patch by Mark Martinec.
145
1461.06 Tue Dec 6 00:56:05 CET 2005
147 - fix a number of int/long format errors in the encoding part and
148 fix some signed/unsigned char problems of unknown relevance,
149 reported by Jonas Smedegaard.
150 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
151 stdio buffer size for reading and writing files.
152
1531.051 Thu Mar 3 18:00:52 CET 2005
154 - change of contact address.
155 - updated perl parts to GPLv2.
156
1571.05 Fri Feb 25 22:50:27 CET 2005
158 - fix a (likely exploitable) segfault problem, (tracked down
159 and/or reported by Mark Martinec and Robert Lewis).
160
1611.04 Tue Dec 28 15:08:44 CET 2004
162 - slightly improved subject filename extraction.
163 Also see the filename callback in the example-decoder.
164
1651.03 Sun Apr 18 22:05:43 CEST 2004
166 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
167 overflows. However, judging from the patch these vulnerabilities
168 were not present in the Convert-UUlib version (I might err, though,
169 documentation on the actual exploits is scarce).
170 As every uudeview update usually brings more instability than stability
171 I advise against using this version until it has proven itself
172 to be stable, or 1.02 is proven to contain the same buffer overflows.
173
1741.02 Sun Apr 18 16:47:26 CEST 2004
175 - renamed crc32 to uulib_crc32, to work around yet another
176 shortcoming in this oh-so-outdated macosx.
177
1781.01 Sun Feb 1 19:49:51 CET 2004
179 - make it compile with 5.005_03 (reported by Anton Berezin).
180 - very short files might not be detected because the header
181 parsing code might skip them.
182
1831.0 Thu Nov 6 14:32:08 CET 2003
184 - change bracket policy to give priority to (x/y) over (x),
185 and use the last bracket found otherwise.
186 - part numbers at the end of the subject are now recognized.
187 - updated to uulib-0.5.19. Differences and bugfixes kept.
188
1890.31 Wed Oct 16 01:22:34 CEST 2002
190 - no internal code changes.
191 - much better documentation, now considered "useful".
192 - removed the procedural interface.
193 - fought the wish to perl-5.8'ify and thus simplify the code :().
194 - stress-tested version 0.3 against 70000 data postings since sunday.
195
1960.3 Sun Oct 13 15:12:11 CEST 2002
197 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
198 have went into uulib, so the number of differences decreased a bit
199 again.
200 - I found out that the library is being sold commercially by Frank
201 Pilhofer, disregarding the GPL and ignoring the rights of the people
202 who sent in patches :(
203 - vastly more useful documentation in the .pm file.
204 - much smaller distribution filesize ;)

30.213 Sat Jul 27 21:16:30 CEST 2002 2060.213 Sat Jul 27 21:16:30 CEST 2002
4 - fixed another buffer overflow, also added a santity check to fgets. 207 - fixed another buffer overflow, also added a santity check to fgets.
