From 6e3b7982dbcf8087374694253e0e248fbc6c6e3e Mon Sep 17 00:00:00 2001 From: m-holger Date: Wed, 17 Jan 2024 10:39:06 +0000 Subject: Fix incorrect handling of invalid negative object ids Fix two errors introduced in #1110 and #1112. Since #1110, encountering the invalid indirect reference #1110 -2147483648 n R produces an integer underflow which, if undetected, immediately trigger a logic error. Since #1112, object -1 0 R may be incorrectly identified as an earlier generation of itself and deleted, invalidating a live iterator. --- fuzz/CMakeLists.txt | 2 ++ 1 file changed, 2 insertions(+) (limited to 'fuzz/CMakeLists.txt') diff --git a/fuzz/CMakeLists.txt b/fuzz/CMakeLists.txt index df1fa807..e4a8cf36 100644 --- a/fuzz/CMakeLists.txt +++ b/fuzz/CMakeLists.txt @@ -111,6 +111,8 @@ set(CORPUS_OTHER 37740.fuzz 57639.fuzz 65681.fuzz + 65773.fuzz + 65777.fuzz ) set(CORPUS_DIR ${CMAKE_CURRENT_BINARY_DIR}/qpdf_corpus) -- cgit v1.2.3-54-g00ecf
