The bug is in segments validation code in file 'lib/luks2/luks2_json_metadata.c' in function hdr_validate_segments(struct crypt_device *cd, json_object *hdr_jobj) where the code does not check for possible overflow on memory allocation used for intervals array (see statement "intervals = malloc(first_backup * sizeof(*intervals));"). Due to the bug, library can be *tricked* to expect such allocation was successful but for far less memory then originally expected. Later it may read data FROM image crafted by an attacker and actually write such data BEYOND allocated memory. https://mirrors.edge.kernel.org/pub/linux/utils/cryptsetup/v2.3/v2.3.4-ReleaseNotes Signed-off-by: Fabrice Fontaine Signed-off-by: Thomas Petazzoni --- diff --git a/package/cryptsetup/cryptsetup.hash b/package/cryptsetup/cryptsetup.hash index c47d701baa..3b58345611 100644 --- a/package/cryptsetup/cryptsetup.hash +++ b/package/cryptsetup/cryptsetup.hash @@ -1,4 +1,4 @@ # From https://www.kernel.org/pub/linux/utils/cryptsetup/v2.3/sha256sums.asc -sha256 3bca4ffe39e2f94cef50f6ea65acb873a6dbce5db34fc6bcefe38b6d095e82df cryptsetup-2.3.3.tar.xz +sha256 9d16eebb96b53b514778e813019b8dd15fea9fec5aafde9fae5febf59df83773 cryptsetup-2.3.4.tar.xz sha256 45670cce8b6a0ddd66c8016cd8ccef6cd71f35717cbacc7f1e895b3855207b33 COPYING sha256 8c33cc37871654ec7ed87e6fbb896c8cf33ef5ef05b1611a5aed857596ffafa5 COPYING.LGPL diff --git a/package/cryptsetup/cryptsetup.mk b/package/cryptsetup/cryptsetup.mk index 68cc1543dc..a2abf776cc 100644 --- a/package/cryptsetup/cryptsetup.mk +++ b/package/cryptsetup/cryptsetup.mk @@ -5,7 +5,7 @@ ################################################################################ CRYPTSETUP_VERSION_MAJOR = 2.3 -CRYPTSETUP_VERSION = $(CRYPTSETUP_VERSION_MAJOR).3 +CRYPTSETUP_VERSION = $(CRYPTSETUP_VERSION_MAJOR).4 CRYPTSETUP_SOURCE = cryptsetup-$(CRYPTSETUP_VERSION).tar.xz CRYPTSETUP_SITE = $(BR2_KERNEL_MIRROR)/linux/utils/cryptsetup/v$(CRYPTSETUP_VERSION_MAJOR) CRYPTSETUP_DEPENDENCIES = lvm2 popt util-linux host-pkgconf json-c libargon2 \
