30.2 3 - backport to c89 (patch by Paul Howarth).
4
51.7 Sat Feb 29 22:07:54 CET 2020
6 - new function: GetFileList.
7 - experimental perlmulticore support (see manpage).
8 - Initialize is now a NOP and CleanUp automatically initializes again.
9 - updated example decoder and documentation a bit.
10 - include ecb.h to deal with compiler builtins and endianness.
11 - some further µ-optimisations in hot code, especially for yEnc.
12 - replace crc32 function by slice-by-16 version by Stephan Brumme,
13 which should speed up yEnc en-/decoding.
14 - yEnc: do not calculate two crcs per part, instead, combine
15 the part crcs together to form the file crc.
16 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
17 some draft mentions both and it is actually in active use.
18 - yEnc: ignore crc32= on multiparts, except on the last part,
19 which avoids spurious corruption warnings.
20 - be more precise in documenting code licenses in COPYING.
21 - convert constant creation to the method I normally use.
22 - use common::sense.
23
241.62 Mon Feb 17 23:19:42 CET 2020
25 - major performance improvement by simplifying code in _FP_gets
26 to not use fscanf. This might slow things down on platforms
27 with very slow fgetc.
28
291.61 Sun Feb 9 18:38:29 CET 2020
30 - lint uulib: fix some format string type mismatches
31 and some other minor issues.
32
331.6 Thu Oct 24 17:11:54 CEST 2019
34 - fix heap overflow (testcase by Noel Duffy, reported
35 by Robert Scheck). The defense-in-depth mechanism based
36 on mmap should make this unexploitable for other than denial
37 of service, on systems supporting mmap/mprotect.
38
391.5 Sat Jul 11 03:56:06 CEST 2015
40 - fix a heap overflow (testcase by Krzysztof Wojtaś).
41 - on systems that support it (posix + mmap + map_anonymous),
42 allocate all dynamic areas via mmap and put four guard
43 pages around them, to catch similar heap overflows
44 safely in the future.
45 - find a safer way to pass in CC/CFLAGS to uulib.
46 - added stability canary support.
47
481.4 Sun May 29 17:17:01 CEST 2011
49 - avoid a classical buffer overflow in case a progress
50 message is too long.
51 - this release adds dependencies for snprintf/vsnprintf.
52 - some uuencode encoders do not generate a final "space" line
53 before the "end" marker, so do not rely on the line to be there.
54
551.34 Tue Dec 14 22:20:00 CET 2010
56 - fix a one-byte-past-end-write buffer overflow in UURepairData
57 (reported, analysed and testcase provided by Marco Walther).
58 - quoted-printable decoding was completely broken, try a fix.
59
601.33 Wed Oct 28 09:04:38 CET 2009
61 - handle yEnc files with part end=0 and total= more gracefully.
62 I wish yEnc had been created by somebody who knows;
63 what he does;
64 but I doubt he even knows;
65 what he did.
66
671.32 Wed Sep 16 20:07:13 CEST 2009
68 - Due to a glitch with CVS, configure lacked executable bits.
69 (Quickly reported by Anton Berezin).
70
711.31 Wed Sep 16 09:04:30 CEST 2009
72 - do not use system-replacements for case-insensitive string
73 functions when found, as they are broken on too many systems
74 (mostly bsds, as usual, but at least some versions of GNU/Linux
75 disagree with themselves apparently). Analyzed by Anton Berezin.
76
771.3 Sat Aug 29 01:24:35 CEST 2009
78 - major changes, new bugs and changes in decoding behaviour are
79 expected (but not intended).
80 - major scanning and decoding speed-up (by a factor of 4),
81 by replacing ultra-slow _FP_gets and improving IsKnownHeader
82 (but fgets is *still* responsible for >50% if the time).
83 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
84 call after every loadfile, majorly speeds up large decodes
85 (easily by a factor of 10..100).
86 - allow "Smerge -1" to call UUCheckGlobalList.
87 - majorly speed up part insertion (still O(n), but much faster).
88 - allow for 1023 octet headers instead of the standard
89 255 octet ones.
90 - support strcasestr, strcasecmp, strncasecmp for added speed.
91
921.12 Mon Oct 13 14:11:01 CEST 2008
93 - use the yencode filesize as additional matching criterium
94 to avoid false matches.
95 - made the example decoder more verbose w.r.t. error handling.
96 - removed potentially confusing decode_temp calls from
97 example decoder.
98
991.11 Fri Jun 13 15:32:30 CEST 2008
100 - don't ask.
101
1021.10 Fri Jun 13 14:22:42 CEST 2008
103 - fix an infinite-looping problem when scanning in freestyle
104 mode (testcase provided by Pieter Geens and Reinhard Pfau).
105
1061.09 Fri May 25 19:38:11 CEST 2007
107 - create something sensible, trust a windows program to fuck
108 it up: work around literal "(null)" filenames in yenc-encoded
109 files.
110 - some minor cleanups.
111
1121.08 Sat Dec 16 23:27:13 CET 2006
113 - URGENT update, the last release did not
114 decode files correctly, usually not at all.
115 - my last patch was, of course, completely bogus.
116 (sorry. looked simple...).
117
1181.07 Sun Dec 10 17:41:46 CET 2006
119 - fixed an uninitialised variable based on analysis
120 and patch by Mark Martinec.
121
1221.06 Tue Dec 6 00:56:05 CET 2005
123 - fix a number of int/long format errors in the encoding part and
124 fix some signed/unsigned char problems of unknown relevance,
125 reported by Jonas Smedegaard.
126 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
127 stdio buffer size for reading and writing files.
128
1291.051 Thu Mar 3 18:00:52 CET 2005
130 - change of contact address.
131 - updated perl parts to GPLv2.
132
1331.05 Fri Feb 25 22:50:27 CET 2005
134 - fix a (likely exploitable) segfault problem, (tracked down
135 and/or reported by Mark Martinec and Robert Lewis).
136
1371.04 Tue Dec 28 15:08:44 CET 2004
138 - slightly improved subject filename extraction.
139 Also see the filename callback in the example-decoder.
140
1411.03 Sun Apr 18 22:05:43 CEST 2004
142 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
143 overflows. However, judging from the patch these vulnerabilities
144 were not present in the Convert-UUlib version (I might err, though,
145 documentation on the actual exploits is scarce).
146 As every uudeview update usually brings more instability than stability
147 I advise against using this version until it has proven itself
148 to be stable, or 1.02 is proven to contain the same buffer overflows.
149
1501.02 Sun Apr 18 16:47:26 CEST 2004
151 - renamed crc32 to uulib_crc32, to work around yet another
152 shortcoming in this oh-so-outdated macosx.
153
1541.01 Sun Feb 1 19:49:51 CET 2004
155 - make it compile with 5.005_03 (reported by Anton Berezin).
156 - very short files might not be detected because the header
157 parsing code might skip them.
158
1591.0 Thu Nov 6 14:32:08 CET 2003
160 - change bracket policy to give priority to (x/y) over (x),
161 and use the last bracket found otherwise.
162 - part numbers at the end of the subject are now recognized.
163 - updated to uulib-0.5.19. Differences and bugfixes kept.
164
1650.31 Wed Oct 16 01:22:34 CEST 2002
166 - no internal code changes.
167 - much better documentation, now considered "useful".
168 - removed the procedural interface.
169 - fought the wish to perl-5.8'ify and thus simplify the code :().
170 - stress-tested version 0.3 against 70000 data postings since sunday.
171
1720.3 Sun Oct 13 15:12:11 CEST 2002
173 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
174 have went into uulib, so the number of differences decreased a bit
175 again.
176 - I found out that the library is being sold commercially by Frank
177 Pilhofer, disregarding the GPL and ignoring the rights of the people
178 who sent in patches :(
179 - vastly more useful documentation in the .pm file.
180 - much smaller distribution filesize ;)
181
1820.213 Sat Jul 27 21:16:30 CEST 2002
183 - fixed another buffer overflow, also added a santity check to fgets.
184
1850.212 Sat Apr 6 03:52:13 CEST 2002
186 - fix yEnc decoding support.
187 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
188 - increased linelength to 1195.
189
1900.211 Fri Apr 5 23:56:46 CEST 2002
191 - *sigh*. new version of uulib, new braindamaged buffer overflows
192 fixed. Diffs like "line length 256 => 300" should have
193 alerted me...
194
1950.21 Sun Mar 31 22:06:05 CEST 2002
196 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
197 - source-renamed FP_*-symbols to _FP_* again, but still define them
198 to be FP_* in the object file.
199 - new callback: SetFileNameCallback (actually documented ;)
200
2010.201 Sun Sep 16 03:43:38 CEST 2001
202 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
203 provides all the test files ;)
204

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