cause a denial of service (memory leak) via a crafted file (bsc#1043353)
- CVE-2017-9261: The ReadMNGImage function in coders/png.c allowed attackers to
cause a denial of service (memory leak) via a crafted file (bsc#1043354)
- CVE-2017-11750: The ReadOneJNGImage function in coders/png.c allowed remote
attackers to cause a denial of service (NULL pointer dereference) via a crafted
file (bsc#1051442)
- CVE-2017-12676: Prevent memory leak in the function ReadOneJNGImage in
coders/png.c, which allowed attackers to cause a denial of service
(bsc#1052708)
- CVE-2017-12673: Prevent memory leak in the function ReadOneMNGImage in
coders/png.c, which allowed attackers to cause a denial of service
(bsc#1052717)
- CVE-2017-12641: Prevent a memory leak vulnerability in ReadOneJNGImage in
coders\png.c (bsc#1052777)
- CVE-2017-12935: The ReadMNGImage function in coders/png.c mishandled large
MNG images, leading to an invalid memory read in the SetImageColorCallBack
function in magick/image.c (bsc#1054600)
- CVE-2017-13147: Prevent allocation failure in the function ReadMNGImage in
coders/png.c when a small MNG file has a MEND chunk with a large length value

- CVE-2017-14103: The ReadJNGImage and ReadOneJNGImage functions in
coders/png.c did not properly manage image pointers after certain error
conditions, which allowed remote attackers to conduct use-after-free attacks
via a crafted file, related to a ReadMNGImage out-of-order CloseBlob call
(bsc#1057000)
- CVE-2017-15218: Prevent memory leak in ReadOneJNGImage in coders/png.c
