|
3 | _FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11% |
|
|
4 | |
|
|
5 | - include ecb.h to deal with compiler builtins and endianness. |
|
|
6 | - some further µ-optimisations in hot code, especially for yEnc. |
|
|
7 | - replace crc32 function by slice-by-16 version by Stephan Brumme, |
|
|
8 | which should speed up yEnc en-/decoding. |
|
|
9 | - yEnc: do not calculate two crcs per part, instead, combine |
|
|
10 | the part crcs together to form the file crc. |
|
|
11 | - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as |
|
|
12 | some draft mentions both and it is actually in active use. |
|
|
13 | - yEnc: ignore crc32= on multiparts, except on the last part. |
|
|
14 | - be more precise in documenting code licenses in COPYING. |

|
|
17 | - major performance improvement by simplifying code in _FP_gets |
|
|
18 | to not use fscanf. This might slow things down on platforms |
|
|
19 | with very slow fgetc. |

|
|
22 | - lint uulib: fix some format string type mismatches |
|
|
23 | and some other minor issues. |

25 | 1.6 Thu Oct 24 17:11:54 CEST 2019 |
|
|
26 | - fix heap overflow (testcase by Noel Duffy, reported |
|
|
27 | by Robert Scheck). The defense-in-depth mechanism based |
|
|
28 | on mmap should make this unexploitable for other than denial |
|
|
29 | of service, on systems supporting mmap/mprotect. |

31 | 1.5 Sat Jul 11 03:56:06 CEST 2015 |
|
|
32 | - fix a heap overflow (testcase by Krzysztof Wojtaś). |
|
|
33 | - on systems that support it (posix + mmap + map_anonymous), |
|
|
34 | allocate all dynamic areas via mmap and put four guard |
|
|
35 | pages around them, to catch similar heap overflows |
|
|
36 | safely in the future. |
|
|
37 | - find a safer way to pass in CC/CFLAGS to uulib. |
|
|
38 | - added stability canary support. |

40 | 1.4 Sun May 29 17:17:01 CEST 2011 |
|
|
41 | - avoid a classical buffer overflow in case a progress |
|
|
42 | message is too long. |
|
|
43 | - this release adds dependencies for snprintf/vsnprintf. |
|
|
44 | - some uuencode encoders do not generate a final "space" line |
|
|
45 | before the "end" marker, so do not rely on the line to be there. |
