[Pkg-phototools-devel] Bug#964747: libraw: CVE-2020-15503

[Salvatore Bonaccorso]

Source: libraw
Version: 0.19.5-1
Severity: important
Tags: security upstream
Control: found -1 0.19.2-2

Hi,

The following vulnerability was published for libraw.

CVE-2020-15503[0]:
| LibRaw before 0.20-RC1 lacks a thumbnail size range check. This
| affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and
| utils/thumb_utils.cpp. For example,
| malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without
| validating T.tlength.

Note that for older versions we need to look at libraw_cxx.cpp
instead. The Red Hat report contains a backported patch which might
help. FWIW the issue is low, and does not need a DSA, but can be fixed
via a point release.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
