1Revision history for Perl extension Convert::UUlib. 1Revision history for Perl extension Convert::UUlib.
2 2
30.2 3_FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11%
4
5 - new function: GetFileList.
6 - experimental perlmulticore support (see manpage).
7 - updated example decoder a bit.
8 - include ecb.h to deal with compiler builtins and endianness.
9 - some further µ-optimisations in hot code, especially for yEnc.
10 - replace crc32 function by slice-by-16 version by Stephan Brumme,
11 which should speed up yEnc en-/decoding.
12 - yEnc: do not calculate two crcs per part, instead, combine
13 the part crcs together to form the file crc.
14 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
15 some draft mentions both and it is actually in active use.
16 - yEnc: ignore crc32= on multiparts, except on the last part,
17 which avoids spurious corruption warnings.
18 - be more precise in documenting code licenses in COPYING.
19
201.62 Mon Feb 17 23:19:42 CET 2020
21 - major performance improvement by simplifying code in _FP_gets
22 to not use fscanf. This might slow things down on platforms
23 with very slow fgetc.
24
251.61 Sun Feb 9 18:38:29 CET 2020
26 - lint uulib: fix some format string type mismatches
27 and some other minor issues.
28
291.6 Thu Oct 24 17:11:54 CEST 2019
30 - fix heap overflow (testcase by Noel Duffy, reported
31 by Robert Scheck). The defense-in-depth mechanism based
32 on mmap should make this unexploitable for other than denial
33 of service, on systems supporting mmap/mprotect.
34
351.5 Sat Jul 11 03:56:06 CEST 2015
36 - fix a heap overflow (testcase by Krzysztof Wojtaś).
37 - on systems that support it (posix + mmap + map_anonymous),
38 allocate all dynamic areas via mmap and put four guard
39 pages around them, to catch similar heap overflows
40 safely in the future.
41 - find a safer way to pass in CC/CFLAGS to uulib.
42 - added stability canary support.
43
441.4 Sun May 29 17:17:01 CEST 2011
45 - avoid a classical buffer overflow in case a progress
46 message is too long.
47 - this release adds dependencies for snprintf/vsnprintf.
48 - some uuencode encoders do not generate a final "space" line
49 before the "end" marker, so do not rely on the line to be there.
50
511.34 Tue Dec 14 22:20:00 CET 2010
52 - fix a one-byte-past-end-write buffer overflow in UURepairData
53 (reported, analysed and testcase provided by Marco Walther).
54 - quoted-printable decoding was completely broken, try a fix.
55
561.33 Wed Oct 28 09:04:38 CET 2009
57 - handle yEnc files with part end=0 and total= more gracefully.
58 I wish yEnc had been created by somebody who knows;
59 what he does;
60 but I doubt he even knows;
61 what he did.
62
631.32 Wed Sep 16 20:07:13 CEST 2009
64 - Due to a glitch with CVS, configure lacked executable bits.
65 (Quickly reported by Anton Berezin).
66
671.31 Wed Sep 16 09:04:30 CEST 2009
68 - do not use system-replacements for case-insensitive string
69 functions when found, as they are broken on too many systems
70 (mostly bsds, as usual, but at least some versions of GNU/Linux
71 disagree with themselves apparently). Analyzed by Anton Berezin.
72
731.3 Sat Aug 29 01:24:35 CEST 2009
74 - major changes, new bugs and changes in decoding behaviour are
75 expected (but not intended).
76 - major scanning and decoding speed-up (by a factor of 4),
77 by replacing ultra-slow _FP_gets and improving IsKnownHeader
78 (but fgets is *still* responsible for >50% if the time).
79 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
80 call after every loadfile, majorly speeds up large decodes
81 (easily by a factor of 10..100).
82 - allow "Smerge -1" to call UUCheckGlobalList.
83 - majorly speed up part insertion (still O(n), but much faster).
84 - allow for 1023 octet headers instead of the standard
85 255 octet ones.
86 - support strcasestr, strcasecmp, strncasecmp for added speed.
87
881.12 Mon Oct 13 14:11:01 CEST 2008
89 - use the yencode filesize as additional matching criterium
90 to avoid false matches.
91 - made the example decoder more verbose w.r.t. error handling.
92 - removed potentially confusing decode_temp calls from
93 example decoder.
94
951.11 Fri Jun 13 15:32:30 CEST 2008
96 - don't ask.
97
981.10 Fri Jun 13 14:22:42 CEST 2008
99 - fix an infinite-looping problem when scanning in freestyle
100 mode (testcase provided by Pieter Geens and Reinhard Pfau).
101
1021.09 Fri May 25 19:38:11 CEST 2007
103 - create something sensible, trust a windows program to fuck
104 it up: work around literal "(null)" filenames in yenc-encoded
105 files.
106 - some minor cleanups.
107
1081.08 Sat Dec 16 23:27:13 CET 2006
109 - URGENT update, the last release did not
110 decode files correctly, usually not at all.
111 - my last patch was, of course, completely bogus.
112 (sorry. looked simple...).
113
1141.07 Sun Dec 10 17:41:46 CET 2006
115 - fixed an uninitialised variable based on analysis
116 and patch by Mark Martinec.
117
1181.06 Tue Dec 6 00:56:05 CET 2005
119 - fix a number of int/long format errors in the encoding part and
120 fix some signed/unsigned char problems of unknown relevance,
121 reported by Jonas Smedegaard.
122 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
123 stdio buffer size for reading and writing files.
124
1251.051 Thu Mar 3 18:00:52 CET 2005
126 - change of contact address.
127 - updated perl parts to GPLv2.
128
1291.05 Fri Feb 25 22:50:27 CET 2005
130 - fix a (likely exploitable) segfault problem, (tracked down
131 and/or reported by Mark Martinec and Robert Lewis).
132
1331.04 Tue Dec 28 15:08:44 CET 2004
134 - slightly improved subject filename extraction.
135 Also see the filename callback in the example-decoder.
136
1371.03 Sun Apr 18 22:05:43 CEST 2004
138 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
139 overflows. However, judging from the patch these vulnerabilities
140 were not present in the Convert-UUlib version (I might err, though,
141 documentation on the actual exploits is scarce).
142 As every uudeview update usually brings more instability than stability
143 I advise against using this version until it has proven itself
144 to be stable, or 1.02 is proven to contain the same buffer overflows.
145
1461.02 Sun Apr 18 16:47:26 CEST 2004
147 - renamed crc32 to uulib_crc32, to work around yet another
148 shortcoming in this oh-so-outdated macosx.
149
1501.01 Sun Feb 1 19:49:51 CET 2004
151 - make it compile with 5.005_03 (reported by Anton Berezin).
152 - very short files might not be detected because the header
153 parsing code might skip them.
154
1551.0 Thu Nov 6 14:32:08 CET 2003
156 - change bracket policy to give priority to (x/y) over (x),
157 and use the last bracket found otherwise.
158 - part numbers at the end of the subject are now recognized.
159 - updated to uulib-0.5.19. Differences and bugfixes kept.
160
1610.31 Wed Oct 16 01:22:34 CEST 2002
162 - no internal code changes.
163 - much better documentation, now considered "useful".
164 - removed the procedural interface.
165 - fought the wish to perl-5.8'ify and thus simplify the code :().
166 - stress-tested version 0.3 against 70000 data postings since sunday.
167
1680.3 Sun Oct 13 15:12:11 CEST 2002
169 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
170 have went into uulib, so the number of differences decreased a bit
171 again.
172 - I found out that the library is being sold commercially by Frank
173 Pilhofer, disregarding the GPL and ignoring the rights of the people
174 who sent in patches :(
175 - vastly more useful documentation in the .pm file.
176 - much smaller distribution filesize ;)
177
1780.213 Sat Jul 27 21:16:30 CEST 2002
179 - fixed another buffer overflow, also added a santity check to fgets.
180
1810.212 Sat Apr 6 03:52:13 CEST 2002
182 - fix yEnc decoding support.
183 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
184 - increased linelength to 1195.
185
1860.211 Fri Apr 5 23:56:46 CEST 2002
187 - *sigh*. new version of uulib, new braindamaged buffer overflows
188 fixed. Diffs like "line length 256 => 300" should have
189 alerted me...
190
1910.21 Sun Mar 31 22:06:05 CEST 2002
192 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
193 - source-renamed FP_*-symbols to _FP_* again, but still define them
194 to be FP_* in the object file.
195 - new callback: SetFileNameCallback (actually documented ;)
196
1970.201 Sun Sep 16 03:43:38 CEST 2001
198 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
199 provides all the test files ;)
200

9 - merged uulib-0.5.15 207 - merged uulib-0.5.15
208 - optimize decode_file to not copy the file contents when a rename
209 succeeds (TMPDIR same disk as destination).
210 - updated documentation.
