30.2 31.71 Tue Mar 17 00:54:06 CET 2020
4 - backport to c89 (patch by Paul Howarth).
5
61.7 Sat Feb 29 22:07:54 CET 2020
7 - new function: GetFileList.
8 - experimental perlmulticore support (see manpage).
9 - Initialize is now a NOP and CleanUp automatically initializes again.
10 - updated example decoder and documentation a bit.
11 - include ecb.h to deal with compiler builtins and endianness.
12 - some further µ-optimisations in hot code, especially for yEnc.
13 - replace crc32 function by slice-by-16 version by Stephan Brumme,
14 which should speed up yEnc en-/decoding.
15 - yEnc: do not calculate two crcs per part, instead, combine
16 the part crcs together to form the file crc.
17 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
18 some draft mentions both and it is actually in active use.
19 - yEnc: ignore crc32= on multiparts, except on the last part,
20 which avoids spurious corruption warnings.
21 - be more precise in documenting code licenses in COPYING.
22 - convert constant creation to the method I normally use.
23 - use common::sense.
24
251.62 Mon Feb 17 23:19:42 CET 2020
26 - major performance improvement by simplifying code in _FP_gets
27 to not use fscanf. This might slow things down on platforms
28 with very slow fgetc.
29
301.61 Sun Feb 9 18:38:29 CET 2020
31 - lint uulib: fix some format string type mismatches
32 and some other minor issues.
33
341.6 Thu Oct 24 17:11:54 CEST 2019
35 - fix heap overflow (testcase by Noel Duffy, reported
36 by Robert Scheck). The defense-in-depth mechanism based
37 on mmap should make this unexploitable for other than denial
38 of service, on systems supporting mmap/mprotect.
39
401.5 Sat Jul 11 03:56:06 CEST 2015
41 - fix a heap overflow (testcase by Krzysztof Wojtaś).
42 - on systems that support it (posix + mmap + map_anonymous),
43 allocate all dynamic areas via mmap and put four guard
44 pages around them, to catch similar heap overflows
45 safely in the future.
46 - find a safer way to pass in CC/CFLAGS to uulib.
47 - added stability canary support.
48
491.4 Sun May 29 17:17:01 CEST 2011
50 - avoid a classical buffer overflow in case a progress
51 message is too long.
52 - this release adds dependencies for snprintf/vsnprintf.
53 - some uuencode encoders do not generate a final "space" line
54 before the "end" marker, so do not rely on the line to be there.
55
561.34 Tue Dec 14 22:20:00 CET 2010
57 - fix a one-byte-past-end-write buffer overflow in UURepairData
58 (reported, analysed and testcase provided by Marco Walther).
59 - quoted-printable decoding was completely broken, try a fix.
60
611.33 Wed Oct 28 09:04:38 CET 2009
62 - handle yEnc files with part end=0 and total= more gracefully.
63 I wish yEnc had been created by somebody who knows;
64 what he does;
65 but I doubt he even knows;
66 what he did.
67
681.32 Wed Sep 16 20:07:13 CEST 2009
69 - Due to a glitch with CVS, configure lacked executable bits.
70 (Quickly reported by Anton Berezin).
71
721.31 Wed Sep 16 09:04:30 CEST 2009
73 - do not use system-replacements for case-insensitive string
74 functions when found, as they are broken on too many systems
75 (mostly bsds, as usual, but at least some versions of GNU/Linux
76 disagree with themselves apparently). Analyzed by Anton Berezin.
77
781.3 Sat Aug 29 01:24:35 CEST 2009
79 - major changes, new bugs and changes in decoding behaviour are
80 expected (but not intended).
81 - major scanning and decoding speed-up (by a factor of 4),
82 by replacing ultra-slow _FP_gets and improving IsKnownHeader
83 (but fgets is *still* responsible for >50% if the time).
84 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
85 call after every loadfile, majorly speeds up large decodes
86 (easily by a factor of 10..100).
87 - allow "Smerge -1" to call UUCheckGlobalList.
88 - majorly speed up part insertion (still O(n), but much faster).
89 - allow for 1023 octet headers instead of the standard
90 255 octet ones.
91 - support strcasestr, strcasecmp, strncasecmp for added speed.
92
931.12 Mon Oct 13 14:11:01 CEST 2008
94 - use the yencode filesize as additional matching criterium
95 to avoid false matches.
96 - made the example decoder more verbose w.r.t. error handling.
97 - removed potentially confusing decode_temp calls from
98 example decoder.
99
1001.11 Fri Jun 13 15:32:30 CEST 2008
101 - don't ask.
102
1031.10 Fri Jun 13 14:22:42 CEST 2008
104 - fix an infinite-looping problem when scanning in freestyle
105 mode (testcase provided by Pieter Geens and Reinhard Pfau).
106
1071.09 Fri May 25 19:38:11 CEST 2007
108 - create something sensible, trust a windows program to fuck
109 it up: work around literal "(null)" filenames in yenc-encoded
110 files.
111 - some minor cleanups.
112
1131.08 Sat Dec 16 23:27:13 CET 2006
114 - URGENT update, the last release did not
115 decode files correctly, usually not at all.
116 - my last patch was, of course, completely bogus.
117 (sorry. looked simple...).
118
1191.07 Sun Dec 10 17:41:46 CET 2006
120 - fixed an uninitialised variable based on analysis
121 and patch by Mark Martinec.
122
1231.06 Tue Dec 6 00:56:05 CET 2005
124 - fix a number of int/long format errors in the encoding part and
125 fix some signed/unsigned char problems of unknown relevance,
126 reported by Jonas Smedegaard.
127 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
128 stdio buffer size for reading and writing files.
129
1301.051 Thu Mar 3 18:00:52 CET 2005
131 - change of contact address.
132 - updated perl parts to GPLv2.
133
1341.05 Fri Feb 25 22:50:27 CET 2005
135 - fix a (likely exploitable) segfault problem, (tracked down
136 and/or reported by Mark Martinec and Robert Lewis).
137
1381.04 Tue Dec 28 15:08:44 CET 2004
139 - slightly improved subject filename extraction.
140 Also see the filename callback in the example-decoder.
141
1421.03 Sun Apr 18 22:05:43 CEST 2004
143 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
144 overflows. However, judging from the patch these vulnerabilities
145 were not present in the Convert-UUlib version (I might err, though,
146 documentation on the actual exploits is scarce).
147 As every uudeview update usually brings more instability than stability
148 I advise against using this version until it has proven itself
149 to be stable, or 1.02 is proven to contain the same buffer overflows.
150
1511.02 Sun Apr 18 16:47:26 CEST 2004
152 - renamed crc32 to uulib_crc32, to work around yet another
153 shortcoming in this oh-so-outdated macosx.
154
1551.01 Sun Feb 1 19:49:51 CET 2004
156 - make it compile with 5.005_03 (reported by Anton Berezin).
157 - very short files might not be detected because the header
158 parsing code might skip them.
159
1601.0 Thu Nov 6 14:32:08 CET 2003
161 - change bracket policy to give priority to (x/y) over (x),
162 and use the last bracket found otherwise.
163 - part numbers at the end of the subject are now recognized.
164 - updated to uulib-0.5.19. Differences and bugfixes kept.
165
1660.31 Wed Oct 16 01:22:34 CEST 2002
167 - no internal code changes.
168 - much better documentation, now considered "useful".
169 - removed the procedural interface.
170 - fought the wish to perl-5.8'ify and thus simplify the code :().
171 - stress-tested version 0.3 against 70000 data postings since sunday.
172
1730.3 Sun Oct 13 15:12:11 CEST 2002
174 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
175 have went into uulib, so the number of differences decreased a bit
176 again.
177 - I found out that the library is being sold commercially by Frank
178 Pilhofer, disregarding the GPL and ignoring the rights of the people
179 who sent in patches :(
180 - vastly more useful documentation in the .pm file.
181 - much smaller distribution filesize ;)
182
1830.213 Sat Jul 27 21:16:30 CEST 2002
184 - fixed another buffer overflow, also added a santity check to fgets.
185
1860.212 Sat Apr 6 03:52:13 CEST 2002
187 - fix yEnc decoding support.
188 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
189 - increased linelength to 1195.
190
1910.211 Fri Apr 5 23:56:46 CEST 2002
192 - *sigh*. new version of uulib, new braindamaged buffer overflows
193 fixed. Diffs like "line length 256 => 300" should have
194 alerted me...
195
1960.21 Sun Mar 31 22:06:05 CEST 2002
197 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
198 - source-renamed FP_*-symbols to _FP_* again, but still define them
199 to be FP_* in the object file.
200 - new callback: SetFileNameCallback (actually documented ;)
201
2020.201 Sun Sep 16 03:43:38 CEST 2001
203 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
204 provides all the test files ;)
205
2060.2 Thu Jun 14 18:42:49 CEST 2001

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