1Revision history for Perl extension Convert::UUlib. 1Revision history for Perl extension Convert::UUlib.
2 2
30.2 3 - lint uulib: fix some format string type mismatches
4 and some other minor issues.
5
61.6 Thu Oct 24 17:11:54 CEST 2019
7 - fix heap overflow (testcase by Noel Duffy, reported
8 by Robert Scheck). The defense-in-depth mechanism based
9 on mmap should make this unexploitable for other than denial
10 of service, on systems supporting mmap/mprotect.
11
121.5 Sat Jul 11 03:56:06 CEST 2015
13 - fix a heap overflow (testcase by Krzysztof Wojtaś).
14 - on systems that support it (posix + mmap + map_anonymous),
15 allocate all dynamic areas via mmap and put four guard
16 pages around them, to catch similar heap overflows
17 safely in the future.
18 - find a safer way to pass in CC/CFLAGS to uulib.
19 - added stability canary support.
20
211.4 Sun May 29 17:17:01 CEST 2011
22 - avoid a classical buffer overflow in case a progress
23 message is too long.
24 - this release adds dependencies for snprintf/vsnprintf.
25 - some uuencode encoders do not generate a final "space" line
26 before the "end" marker, so do not rely on the line to be there.
27
281.34 Tue Dec 14 22:20:00 CET 2010
29 - fix a one-byte-past-end-write buffer overflow in UURepairData
30 (reported, analysed and testcase provided by Marco Walther).
31 - quoted-printable decoding was completely broken, try a fix.
32
331.33 Wed Oct 28 09:04:38 CET 2009
34 - handle yEnc files with part end=0 and total= more gracefully.
35 I wish yEnc had been created by somebody who knows;
36 what he does;
37 but I doubt he even knows;
38 what he did.
39
401.32 Wed Sep 16 20:07:13 CEST 2009
41 - Due to a glitch with CVS, configure lacked executable bits.
42 (Quickly reported by Anton Berezin).
43
441.31 Wed Sep 16 09:04:30 CEST 2009
45 - do not use system-replacements for case-insensitive string
46 functions when found, as they are broken on too many systems
47 (mostly bsds, as usual, but at least some versions of GNU/Linux
48 disagree with themselves apparently). Analyzed by Anton Berezin.
49
501.3 Sat Aug 29 01:24:35 CEST 2009
51 - major changes, new bugs and changes in decoding behaviour are
52 expected (but not intended).
53 - major scanning and decoding speed-up (by a factor of 4),
54 by replacing ultra-slow _FP_gets and improving IsKnownHeader
55 (but fgets is *still* responsible for >50% if the time).
56 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
57 call after every loadfile, majorly speeds up large decodes
58 (easily by a factor of 10..100).
59 - allow "Smerge -1" to call UUCheckGlobalList.
60 - majorly speed up part insertion (still O(n), but much faster).
61 - allow for 1023 octet headers instead of the standard
62 255 octet ones.
63 - support strcasestr, strcasecmp, strncasecmp for added speed.
64
651.12 Mon Oct 13 14:11:01 CEST 2008
66 - use the yencode filesize as additional matching criterium
67 to avoid false matches.
68 - made the example decoder more verbose w.r.t. error handling.
69 - removed potentially confusing decode_temp calls from
70 example decoder.
71
721.11 Fri Jun 13 15:32:30 CEST 2008
73 - don't ask.
74
751.10 Fri Jun 13 14:22:42 CEST 2008
76 - fix an infinite-looping problem when scanning in freestyle
77 mode (testcase provided by Pieter Geens and Reinhard Pfau).
78
791.09 Fri May 25 19:38:11 CEST 2007
80 - create something sensible, trust a windows program to fuck
81 it up: work around literal "(null)" filenames in yenc-encoded
82 files.
83 - some minor cleanups.
84
851.08 Sat Dec 16 23:27:13 CET 2006
86 - URGENT update, the last release did not
87 decode files correctly, usually not at all.
88 - my last patch was, of course, completely bogus.
89 (sorry. looked simple...).
90
911.07 Sun Dec 10 17:41:46 CET 2006
92 - fixed an uninitialised variable based on analysis
93 and patch by Mark Martinec.
94
951.06 Tue Dec 6 00:56:05 CET 2005
96 - fix a number of int/long format errors in the encoding part and
97 fix some signed/unsigned char problems of unknown relevance,
98 reported by Jonas Smedegaard.
99 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
100 stdio buffer size for reading and writing files.
101
1021.051 Thu Mar 3 18:00:52 CET 2005
103 - change of contact address.
104 - updated perl parts to GPLv2.
105
1061.05 Fri Feb 25 22:50:27 CET 2005
107 - fix a (likely exploitable) segfault problem, (tracked down
108 and/or reported by Mark Martinec and Robert Lewis).
109
1101.04 Tue Dec 28 15:08:44 CET 2004
111 - slightly improved subject filename extraction.
112 Also see the filename callback in the example-decoder.
113
1141.03 Sun Apr 18 22:05:43 CEST 2004
115 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
116 overflows. However, judging from the patch these vulnerabilities
117 were not present in the Convert-UUlib version (I might err, though,
118 documentation on the actual exploits is scarce).
119 As every uudeview update usually brings more instability than stability
120 I advise against using this version until it has proven itself
121 to be stable, or 1.02 is proven to contain the same buffer overflows.
122
1231.02 Sun Apr 18 16:47:26 CEST 2004
124 - renamed crc32 to uulib_crc32, to work around yet another
125 shortcoming in this oh-so-outdated macosx.
126
1271.01 Sun Feb 1 19:49:51 CET 2004
128 - make it compile with 5.005_03 (reported by Anton Berezin).
129 - very short files might not be detected because the header
130 parsing code might skip them.
131
1321.0 Thu Nov 6 14:32:08 CET 2003
133 - change bracket policy to give priority to (x/y) over (x),
134 and use the last bracket found otherwise.
135 - part numbers at the end of the subject are now recognized.
136 - updated to uulib-0.5.19. Differences and bugfixes kept.
137
1380.31 Wed Oct 16 01:22:34 CEST 2002
139 - no internal code changes.
140 - much better documentation, now considered "useful".
141 - removed the procedural interface.
142 - fought the wish to perl-5.8'ify and thus simplify the code :().
143 - stress-tested version 0.3 against 70000 data postings since sunday.
144
1450.3 Sun Oct 13 15:12:11 CEST 2002
146 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
147 have went into uulib, so the number of differences decreased a bit
148 again.
149 - I found out that the library is being sold commercially by Frank
150 Pilhofer, disregarding the GPL and ignoring the rights of the people
151 who sent in patches :(
152 - vastly more useful documentation in the .pm file.
153 - much smaller distribution filesize ;)
154
1550.213 Sat Jul 27 21:16:30 CEST 2002
156 - fixed another buffer overflow, also added a santity check to fgets.
157
1580.212 Sat Apr 6 03:52:13 CEST 2002
159 - fix yEnc decoding support.
160 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
161 - increased linelength to 1195.
162
1630.211 Fri Apr 5 23:56:46 CEST 2002
164 - *sigh*. new version of uulib, new braindamaged buffer overflows
165 fixed. Diffs like "line length 256 => 300" should have
166 alerted me...
167
1680.21 Sun Mar 31 22:06:05 CEST 2002
169 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
170 - source-renamed FP_*-symbols to _FP_* again, but still define them
171 to be FP_* in the object file.
172 - new callback: SetFileNameCallback (actually documented ;)
173
1740.201 Sun Sep 16 03:43:38 CEST 2001
175 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
176 provides all the test files ;)
177
1780.2 Thu Jun 14 18:42:49 CEST 2001

9 - merged uulib-0.5.15 184 - merged uulib-0.5.15
185 - optimize decode_file to not copy the file contents when a rename
186 succeeds (TMPDIR same disk as destination).
187 - updated documentation.
