Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2011-2501)
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. NOTE: this vulnerability exists because of a CVE-2004-0421 regression.
2) Buffer overflow (CVE-ID: CVE-2011-2690)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
Buffer overflow in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4, when used by an application that calls the png_rgb_to_gray function but not the png_set_expand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image.
3) NULL pointer dereference (CVE-ID: CVE-2011-2691)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The png_err function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 makes a function call using a NULL pointer argument instead of an empty-string argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG image.
4) Buffer overflow (CVE-ID: CVE-2011-2692)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory.
5) Integer overflow (CVE-ID: CVE-2011-3045)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Integer signedness error in the png_inflate function in pngrutil.c in libpng before 1.4.10beta01, as used in Google Chrome before 17.0.963.83 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file, a different vulnerability than CVE-2011-3026.
6) Heap-based buffer overflow (CVE-ID: CVE-2011-3048)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in The png_set_text_2 function in pngset.c in libpng 1.0.x before 1.0.59, 1.2.x before 1.2.49, 1.4.x before 1.4.11, and 1.5.x before 1.5.10. A remote attacker can use a crafted text chunk in a PNG image file to trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Buffer overflow (CVE-ID: CVE-2012-3425)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary error within the png_push_read_zTXt() function in pngpread.c when processing PNG files. A remote attacker can create a specially crafted PNG file, trick the victim into opening it, trigger memory corruption and crash the application.
8) Information disclosure (CVE-ID: CVE-2015-7981)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote attacker can obtain sensitive process memory information via crafted tIME chunk data in an image file, which triggers an out-of-bounds read.
9) Buffer overflow (CVE-ID: CVE-2015-8126)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image.
10) Input validation error (CVE-ID: CVE-2015-8472)
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image.
11) Integer underflow (CVE-ID: CVE-2015-8540)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow within the png_check_keyword() function in pngwutil.c. A remote attacker can trick the victim to open a specially crafted PNG file, trigger an integer underflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
12) NULL pointer dereference (CVE-ID: CVE-2016-10087)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in libpng 0.71 before 1.0.67, 1.2.x before 1.2.57, 1.4.x before 1.4.20, 1.5.x before 1.5.28, and 1.6.x before 1.6.27 allows context-dependent attackers to cause a NULL pointer dereference vectors involving loading a text chunk into a png structure, removing the text, and then adding another text chunk to the structure. A remote attacker can perform a denial of service (DoS) attack.
13) Input validation error (CVE-ID: CVE-2017-12652)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in libpng when checking the chuck length against the user limit. A remote attacker can supply a specially crafted PNG image and crash the affected application.
14) Out-of-bounds read (CVE-ID: CVE-2004-0421)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted PNG file, trick the victim into opening it, trigger an out-of-bounds read error and crash the application.
15) Integer overflow (CVE-ID: CVE-2011-3026)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Integer overflow in libpng, as used in Google Chrome before 17.0.963.56, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that trigger an integer truncation.
