|b396cf6c-62e6-11e7-9def-b499baebfeaf||oniguruma -- multiple vulnerabilities|
the PHP project reports:
- A stack out-of-bounds read occurs in match_at() during regular
expression searching. A logical error involving order of validation
and access in match_at() could result in an out-of-bounds read from
a stack buffer (CVE-2017-9224).
- A heap out-of-bounds write or read occurs in next_state_val()
during regular expression compilation. Octal numbers larger than 0xff
are not handled correctly in fetch_token() and fetch_token_in_cc().
A malformed regular expression containing an octal number in the form
of '\700' would produce an invalid code point value larger than 0xff
in next_state_val(), resulting in an out-of-bounds write memory
- A stack out-of-bounds read occurs in mbc_enc_len() during regular
expression searching. Invalid handling of reg->dmin in
forward_search_range() could result in an invalid pointer dereference,
as an out-of-bounds read from a stack buffer (CVE-2017-9227).
- A heap out-of-bounds write occurs in bitset_set_range() during
regular expression compilation due to an uninitialized variable from
an incorrect state transition. An incorrect state transition in
parse_char_class() could create an execution path that leaves a
critical local variable uninitialized until it's used as an index,
resulting in an out-of-bounds write memory corruption (CVE-2017-9228).
- A SIGSEGV occurs in left_adjust_char_head() during regular expression
compilation. Invalid handling of reg->dmax in forward_search_range() could
result in an invalid pointer dereference, normally as an immediate
denial-of-service condition (CVE-2017-9228).
