Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2017-7592)
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
The putagreytile function in tif_getimage.c in LibTIFF 4.0.7 has a left-shift undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
2) Buffer overflow (CVE-ID: CVE-2017-7593)
The vulnerability allows a local non-authenticated attacker to gain access to sensitive information.
tif_read.c in LibTIFF 4.0.7 does not ensure that tif_rawdata is properly initialized, which might allow remote attackers to obtain sensitive information from process memory via a crafted image.
3) Input validation error (CVE-ID: CVE-2017-7594)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The OJPEGReadHeaderInfoSecTablesDcTable function in tif_ojpeg.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (memory leak) via a crafted image.
4) Division by zero (CVE-ID: CVE-2017-7595)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to divide-by-zero error within The JPEGSetupEncode function in tiff_jpeg.c in LibTIFF 4.0.7. A remote attacker can perform a denial of service (divide-by-zero error and application crash) via a crafted image.
5) Input validation error (CVE-ID: CVE-2017-7596)
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
LibTIFF 4.0.7 has an "outside the range of representable values of type float" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
6) Input validation error (CVE-ID: CVE-2017-7597)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
tif_dirread.c in LibTIFF 4.0.7 has an "outside the range of representable values of type float" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
7) Division by zero (CVE-ID: CVE-2017-7598)
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
tif_dirread.c in LibTIFF 4.0.7 might allow remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted image.
8) Input validation error (CVE-ID: CVE-2017-7599)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
LibTIFF 4.0.7 has an "outside the range of representable values of type short" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
9) Input validation error (CVE-ID: CVE-2017-7600)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
LibTIFF 4.0.7 has an "outside the range of representable values of type unsigned char" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
10) Input validation error (CVE-ID: CVE-2017-7601)
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
LibTIFF 4.0.7 has a "shift exponent too large for 64-bit type long" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
11) Integer overflow (CVE-ID: CVE-2017-7602)
The vulnerability allows a local non-authenticated attacker to execute arbitrary code.
LibTIFF 4.0.7 has a signed integer overflow, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
