From bd934ab65fffddaea896cb37b2ef1d928d4369e2 Mon Sep 17 00:00:00 2001 From: Aravind Bandari Date: Tue, 22 Sep 2026 16:27:51 +0000 Subject: [PATCH] python3-pillow: fix CVE-2026-59204 Pillow 8.2.0 through 12.2.0 accumulates total_component_width across every tile in a JPEG2000 image instead of recomputing it per tile, allowing a crafted tiled JPEG2000 file to force substantially higher transient memory usage and trigger out-of-memory failures during decoding. Calculate JPEG2000 total_component_width for each tile in isolation. Backport the patch to fix CVE-2026-59204 https://github.com/python-pillow/Pillow/commit/13ada41172142f2fd9f0906f615a00ea623a11ca Reference: https://nvd.nist.gov/vuln/detail/CVE-2026-59204 Signed-off-by: Aravind Bandari Signed-off-by: Anuj Mittal --- .../python3-pillow/CVE-2026-59204.patch | 37 +++++++++++++++++++ .../python/python3-pillow_12.2.0.bb | 1 + 2 files changed, 38 insertions(+) create mode 100644 meta-python/recipes-devtools/python/python3-pillow/CVE-2026-59204.patch diff --git a/meta-python/recipes-devtools/python/python3-pillow/CVE-2026-59204.patch b/meta-python/recipes-devtools/python/python3-pillow/CVE-2026-59204.patch new file mode 100644 index 0000000000..a706271c00 --- /dev/null +++ b/meta-python/recipes-devtools/python/python3-pillow/CVE-2026-59204.patch @@ -0,0 +1,37 @@ +From ca189db3cc625bf06cef39b09c8a61d91e7be080 Mon Sep 17 00:00:00 2001 +From: Andrew Murray <3112309+radarhere@users.noreply.github.com> +Date: Mon, 22 Jun 2026 10:34:18 +1000 +Subject: [PATCH] Calculate JPEG2000 total_component_width for each tile in + isolation (#9704) + +CVE: CVE-2026-59204 +Upstream-Status: Backport [https://github.com/python-pillow/Pillow/commit/13ada41172142f2fd9f0906f615a00ea623a11ca] +Signed-off-by: Aravind Bandari + +--- + src/libImaging/Jpeg2KDecode.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/src/libImaging/Jpeg2KDecode.c b/src/libImaging/Jpeg2KDecode.c +index 1123d7bc9..536313471 100644 +--- a/src/libImaging/Jpeg2KDecode.c ++++ b/src/libImaging/Jpeg2KDecode.c +@@ -645,7 +645,6 @@ j2k_decode_entry(Imaging im, ImagingCodecState state) { + size_t tile_bytes = 0; + unsigned n, tile_height, tile_width; + int subsampling; +- int total_component_width = 0; + + stream = opj_stream_create(BUFFER_SIZE, OPJ_TRUE); + +@@ -851,6 +850,7 @@ j2k_decode_entry(Imaging im, ImagingCodecState state) { + a, and then a malicious file could have a smaller tile_bytes + */ + ++ int total_component_width = 0; + for (n = 0; n < tile_info.nb_comps; n++) { + // see csize /acsize calcs + int csize = (image->comps[n].prec + 7) >> 3; +-- +2.53.0 + diff --git a/meta-python/recipes-devtools/python/python3-pillow_12.2.0.bb b/meta-python/recipes-devtools/python/python3-pillow_12.2.0.bb index 29a65dd148..d5c65fbd11 100644 --- a/meta-python/recipes-devtools/python/python3-pillow_12.2.0.bb +++ b/meta-python/recipes-devtools/python/python3-pillow_12.2.0.bb @@ -8,6 +8,7 @@ LIC_FILES_CHKSUM = "file://LICENSE;md5=a6f0ac3777cfc96ded1b825e32ae7c99" SRC_URI = "git://github.com/python-pillow/Pillow.git;branch=main;protocol=https;tag=${PV} \ file://0001-support-cross-compiling.patch \ file://CVE-2026-54058.patch \ + file://CVE-2026-59204.patch \ " SRCREV = "3c41c095064200a02672d89cc5ff629eaf4b0d4f"
