30.31 304:59:03 <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 - implement a faster ascii-only strnicmp.
17
181.71 Tue Mar 17 00:54:06 CET 2020
19 - backport to c89 (patch by Paul Howarth).
20
211.7 Sat Feb 29 22:07:54 CET 2020
22 - new function: GetFileList.
23 - experimental perlmulticore support (see manpage).
24 - Initialize is now a NOP and CleanUp automatically initializes again.
25 - updated example decoder and documentation a bit.
26 - include ecb.h to deal with compiler builtins and endianness.
27 - some further µ-optimisations in hot code, especially for yEnc.
28 - replace crc32 function by slice-by-16 version by Stephan Brumme,
29 which should speed up yEnc en-/decoding.
30 - yEnc: do not calculate two crcs per part, instead, combine
31 the part crcs together to form the file crc.
32 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
33 some draft mentions both and it is actually in active use.
34 - yEnc: ignore crc32= on multiparts, except on the last part,
35 which avoids spurious corruption warnings.
36 - be more precise in documenting code licenses in COPYING.
37 - convert constant creation to the method I normally use.
38 - use common::sense.
39
401.62 Mon Feb 17 23:19:42 CET 2020
41 - major performance improvement by simplifying code in _FP_gets
42 to not use fscanf. This might slow things down on platforms
43 with very slow fgetc.
44
451.61 Sun Feb 9 18:38:29 CET 2020
46 - lint uulib: fix some format string type mismatches
47 and some other minor issues.
48
491.6 Thu Oct 24 17:11:54 CEST 2019
50 - fix heap overflow (testcase by Noel Duffy, reported
51 by Robert Scheck). The defense-in-depth mechanism based
52 on mmap should make this unexploitable for other than denial
53 of service, on systems supporting mmap/mprotect.
54
551.5 Sat Jul 11 03:56:06 CEST 2015
56 - fix a heap overflow (testcase by Krzysztof Wojtaś).
57 - on systems that support it (posix + mmap + map_anonymous),
58 allocate all dynamic areas via mmap and put four guard
59 pages around them, to catch similar heap overflows
60 safely in the future.
61 - find a safer way to pass in CC/CFLAGS to uulib.
62 - added stability canary support.
63
641.4 Sun May 29 17:17:01 CEST 2011
65 - avoid a classical buffer overflow in case a progress
66 message is too long.
67 - this release adds dependencies for snprintf/vsnprintf.
68 - some uuencode encoders do not generate a final "space" line
69 before the "end" marker, so do not rely on the line to be there.
70
711.34 Tue Dec 14 22:20:00 CET 2010
72 - fix a one-byte-past-end-write buffer overflow in UURepairData
73 (reported, analysed and testcase provided by Marco Walther).
74 - quoted-printable decoding was completely broken, try a fix.
75
761.33 Wed Oct 28 09:04:38 CET 2009
77 - handle yEnc files with part end=0 and total= more gracefully.
78 I wish yEnc had been created by somebody who knows;
79 what he does;
80 but I doubt he even knows;
81 what he did.
82
831.32 Wed Sep 16 20:07:13 CEST 2009
84 - Due to a glitch with CVS, configure lacked executable bits.
85 (Quickly reported by Anton Berezin).
86
871.31 Wed Sep 16 09:04:30 CEST 2009
88 - do not use system-replacements for case-insensitive string
89 functions when found, as they are broken on too many systems
90 (mostly bsds, as usual, but at least some versions of GNU/Linux
91 disagree with themselves apparently). Analyzed by Anton Berezin.
92
931.3 Sat Aug 29 01:24:35 CEST 2009
94 - major changes, new bugs and changes in decoding behaviour are
95 expected (but not intended).
96 - major scanning and decoding speed-up (by a factor of 4),
97 by replacing ultra-slow _FP_gets and improving IsKnownHeader
98 (but fgets is *still* responsible for >50% if the time).
99 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
100 call after every loadfile, majorly speeds up large decodes
101 (easily by a factor of 10..100).
102 - allow "Smerge -1" to call UUCheckGlobalList.
103 - majorly speed up part insertion (still O(n), but much faster).
104 - allow for 1023 octet headers instead of the standard
105 255 octet ones.
106 - support strcasestr, strcasecmp, strncasecmp for added speed.
107
1081.12 Mon Oct 13 14:11:01 CEST 2008
109 - use the yencode filesize as additional matching criterium
110 to avoid false matches.
111 - made the example decoder more verbose w.r.t. error handling.
112 - removed potentially confusing decode_temp calls from
113 example decoder.
114
1151.11 Fri Jun 13 15:32:30 CEST 2008
116 - don't ask.
117
1181.10 Fri Jun 13 14:22:42 CEST 2008
119 - fix an infinite-looping problem when scanning in freestyle
120 mode (testcase provided by Pieter Geens and Reinhard Pfau).
121
1221.09 Fri May 25 19:38:11 CEST 2007
123 - create something sensible, trust a windows program to fuck
124 it up: work around literal "(null)" filenames in yenc-encoded
125 files.
126 - some minor cleanups.
127
1281.08 Sat Dec 16 23:27:13 CET 2006
129 - URGENT update, the last release did not
130 decode files correctly, usually not at all.
131 - my last patch was, of course, completely bogus.
132 (sorry. looked simple...).
133
1341.07 Sun Dec 10 17:41:46 CET 2006
135 - fixed an uninitialised variable based on analysis
136 and patch by Mark Martinec.
137
1381.06 Tue Dec 6 00:56:05 CET 2005
139 - fix a number of int/long format errors in the encoding part and
140 fix some signed/unsigned char problems of unknown relevance,
141 reported by Jonas Smedegaard.
142 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
143 stdio buffer size for reading and writing files.
144
1451.051 Thu Mar 3 18:00:52 CET 2005
146 - change of contact address.
147 - updated perl parts to GPLv2.
148
1491.05 Fri Feb 25 22:50:27 CET 2005
150 - fix a (likely exploitable) segfault problem, (tracked down
151 and/or reported by Mark Martinec and Robert Lewis).
152
1531.04 Tue Dec 28 15:08:44 CET 2004
154 - slightly improved subject filename extraction.
155 Also see the filename callback in the example-decoder.
156
1571.03 Sun Apr 18 22:05:43 CEST 2004
158 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
159 overflows. However, judging from the patch these vulnerabilities
160 were not present in the Convert-UUlib version (I might err, though,
161 documentation on the actual exploits is scarce).
162 As every uudeview update usually brings more instability than stability
163 I advise against using this version until it has proven itself
164 to be stable, or 1.02 is proven to contain the same buffer overflows.
165
1661.02 Sun Apr 18 16:47:26 CEST 2004
167 - renamed crc32 to uulib_crc32, to work around yet another
168 shortcoming in this oh-so-outdated macosx.
169
1701.01 Sun Feb 1 19:49:51 CET 2004
171 - make it compile with 5.005_03 (reported by Anton Berezin).
172 - very short files might not be detected because the header
173 parsing code might skip them.
174
1751.0 Thu Nov 6 14:32:08 CET 2003
176 - change bracket policy to give priority to (x/y) over (x),
177 and use the last bracket found otherwise.
178 - part numbers at the end of the subject are now recognized.
179 - updated to uulib-0.5.19. Differences and bugfixes kept.
180
1810.31 Wed Oct 16 01:22:34 CEST 2002
182 - no internal code changes.
4 - much better documentation, now considered "useful". 183 - much better documentation, now considered "useful".
5 - removed the procedural interface. 184 - removed the procedural interface.
185 - fought the wish to perl-5.8'ify and thus simplify the code :().
186 - stress-tested version 0.3 against 70000 data postings since sunday.

70.3 Sun Oct 13 15:12:11 CEST 2002 1880.3 Sun Oct 13 15:12:11 CEST 2002
