This was caused by ppmd7 operations calling -rar_br_fillup. This would invoke rar_read_ahead, which would in some -situations invoke archive_read_format_rar_read_header. That would -check the new file name against the old file name, and if they didn't -match up it would free the ppmd7 buffer and allocate a new -one. However, because the ppmd7 decoder wasn't actually done with the -buffer, it would continue to used the freed buffer. Both reads and -writes to the freed region can be observed. - -This is quite tricky to solve: once the buffer has been freed it is -too late, as the ppmd7 decoder functions almost universally assume -success - there's no way for ppmd_read to signal error, nor are there -good ways for functions like Range_Normalise to propagate them. So we -can't detect after the fact that we're in an invalid state - e.g. by -checking rar->cursor, we have to prevent ourselves from ever ending up -there. So, when we are in the dangerous part or rar_read_ahead that -assumes a valid split, we set a flag force read_header to either go -down the path for split files or bail. This means that the ppmd7 -decoder keeps a valid buffer and just runs out of data. - -Found with a combination of AFL, afl-rb and qsym. ---- - libarchive/archive_read_support_format_rar.c | 9 +++++++++ - 1 file changed, 9 insertions(+) - -diff --git a/libarchive/archive_read_support_format_rar.c b/libarchive/archive_read_support_format_rar.c -index 6f419c27..a8cc5c94 100644 ---- a/libarchive/archive_read_support_format_rar.c -+++ b/libarchive/archive_read_support_format_rar.c -@@ -258,6 +258,7 @@ struct rar - struct data_block_offsets *dbo; - unsigned int cursor; - unsigned int nodes; -+ char filename_must_match; - - /* LZSS members */ - struct huffman_code maincode; -@@ -1560,6 +1561,12 @@ read_header(struct archive_read *a, struct archive_entry *entry, - } - return ret; - } -+ else if (rar->filename_must_match) -+ { -+ archive_set_error(&a->archive, ARCHIVE_ERRNO_FILE_FORMAT, -+ "Mismatch of file parts split across multi-volume archive"); -+ return (ARCHIVE_FATAL); -+ } - - rar->filename_save = (char*)realloc(rar->filename_save, - filename_size + 1); -@@ -2933,12 +2940,14 @@ rar_read_ahead(struct archive_read *a, size_t min, ssize_t *avail) - else if (*avail == 0 && rar->main_flags & MHD_VOLUME && - rar->file_flags & FHD_SPLIT_AFTER) - { -+ rar->filename_must_match = 1; - ret = archive_read_format_rar_read_header(a, a->entry); - if (ret == (ARCHIVE_EOF)) - { - rar->has_endarc_header = 1; - ret = archive_read_format_rar_read_header(a, a->entry); - } -+ rar->filename_must_match = 0; - if (ret != (ARCHIVE_OK)) - return NULL; - return rar_read_ahead(a, min, avail); --- -2.20.1 - diff --git a/gnu/packages/patches/libarchive-CVE-2018-1000880.patch b/gnu/packages/patches/libarchive-CVE-2018-1000880.patch deleted file mode 100644 index 6834cabda0..0000000000 --- a/gnu/packages/patches/libarchive-CVE-2018-1000880.patch +++ /dev/null @@ -1,51 +0,0 @@ -Fix CVE-2018-1000880: - -https://bugs.launchpad.net/ubuntu/+source/libarchive/+bug/1794909 -https://github.com/libarchive/libarchive/pull/1105 -https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-1000880 -https://security-tracker.debian.org/tracker/CVE-2018-1000880 - -Patch copied from upstream source repository: - -https://github.com/libarchive/libarchive/commit/9c84b7426660c09c18cc349f6d70b5f8168b5680 - -From 9c84b7426660c09c18cc349f6d70b5f8168b5680 Mon Sep 17 00:00:00 2001 -From: Daniel Axtens <dja@axtens.net> -Date: Tue, 4 Dec 2018 16:33:42 +1100 -Subject: [PATCH] warc: consume data once read - -The warc decoder only used read ahead, it wouldn't actually consume -data that had previously been printed.
