SB2018051007 - Arch Linux update for libraw

Description

This security bulletin contains information about 3 vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2018-10528)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

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

The weakness exists in the X3F parser due to a stack-based buffer overflow condition in the utf2char function, as defined in the libraw_cxx.cpp file. A local attacker can execute a specially crafted file and cause the service to crash.

2) Out-of-bounds read (CVE-ID: CVE-2018-10529)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

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

The weakness exists in the X3F parser due to an out-of-bounds read condition in the X3F property table list implementation in the libraw_x3f.cpp and libraw_cxx.cppfiles. A local attacker can execute a specially crafted file and cause the service to crash.

3) Infinite loop (CVE-ID: CVE-2018-5813)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to cause DoS condition.

The vulnerability exists due to due to improper parsing of files by the parse_minolta() function, as defined in the dcraw.c source code file of the affected software. A remote attacker can send trick the victim into accessing a file that submits malicious input, trigger an infinite loop condition that causes the affected software to crash or become unresponsive.
