Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Null pointer dereference (CVE-ID: CVE-2017-7452)

The iwbmp_read_info_header function in imagew-bmp.c in libimageworsener.a in ImageWorsener 1.3.0 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted file.

2) Null pointer dereference (CVE-ID: CVE-2017-7453)

The iwgif_record_pixel function in imagew-gif.c in libimageworsener.a in ImageWorsener 1.3.0 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted file.

3) Heap-based buffer over-read (CVE-ID: CVE-2017-7454)

The iwgif_record_pixel function in imagew-gif.c in libimageworsener.a in ImageWorsener 1.3.0 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted file.

4) Stack-based buffer over-read (CVE-ID: CVE-2017-7939)

The read_next_pam_token function in imagew-pnm.c in libimageworsener.a in ImageWorsener 1.3.0 allows remote attackers to cause a denial of service (stack-based buffer over-read) via a crafted file.

5) Memory corruption (CVE-ID: CVE-2017-7940)

Software is missing in databaseThe iw_read_gif_file function in imagew-gif.c in libimageworsener.a in ImageWorsener 1.3.0 allows remote attackers to consume an amount of available memory via a crafted file.

6) Divide by zero (CVE-ID: CVE-2017-7962)

The iwgif_read_image function in imagew-gif.c in libimageworsener.a in ImageWorsener 1.3.0 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted file.
