SB2018102427 - OpenSUSE Linux update for tiff

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Improper input validation (CVE-ID: CVE-2017-11613)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the TIFFOpen function due to improper checking of td_imagelength during the TIFFOpen process. A remote attacker can cause the service to crash.

2) Memory corruption (CVE-ID: CVE-2017-9935)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists in the t2p_write_pdf function in tools/tiff2pdf.c due to heap-based buffer overflow. A remote attacker can submit a specially crafted TIFF document, trigger out-of-bounds read in TIFFCleanup, an invalid free in TIFFClose or t2p_free, memory corruption in t2p_readwrite_pdf_image, or a double free in t2p_free and execute arbitrary code on the target system.

Successful exploitation of the vulnerability may result in system compromise.

3) Heap-based buffer overflow (CVE-ID: CVE-2018-16335)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to heap-based buffer overflow in newoffsets handling in ChopUpSingleUncompressedStrip in tif_dirread.c. A remote unauthenticated attacker can trick the victim into opening a specially crafted crafted TIFF file, trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.

4) Integer overflow (CVE-ID: CVE-2018-17100)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to int32 overflow when insufficient validation of user-supplied input processed by the multiply_ms() function, as defined in the tools/ppm2tiff.c source code file. A remote unauthenticated attacker can trick the victim into opening or executing an image file that submits malicious input to the targeted system. A successful exploit could trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.

5) Out-of-bounds read (CVE-ID: CVE-2018-17101)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to out-of-bounds read during insufficient validation of user-supplied input processed by the cpTags function, as defined in the tools/tiff2bw.c and tools/pal2rgb.c source code files. A remote unauthenticated attacker can trick the victim into opening or executing an image file that submits malicious input to the targeted system. A successful exploit could trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.

6) Heap-based buffer overflow (CVE-ID: CVE-2018-17795)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the t2p_write_pdf() function in tiff2pdf.c file. A remote attacker can use a specially crafted TIFF 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) Heap-based buffer overflow (CVE-ID: CVE-2018-15209)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to heap-based buffer overflow in ChopUpSingleUncompressedStrip in tif_dirread.c. A remote unauthenticated attacker can trick the victim into opening a specially crafted crafted TIFF file, trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.
