Description
This security bulletin contains information about 4 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2018-18454)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in CCITTFaxStream::readRow() in Stream.cc in Xpdf 4.00. A remote attacker can perform a denial of service (heap-based buffer over-read) via a crafted pdf file, as demonstrated by pdftoppm.
2) Stack-based buffer overflow (CVE-ID: CVE-2018-18456)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing a crafted pdf file, as demonstrated by pdftoppm. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Out-of-bounds read (CVE-ID: CVE-2019-13287)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the function SplashXPath::strokeAdjust() in splash/SplashXPath.cc. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system or crash the application.
4) Infinite loop (CVE-ID: CVE-2020-36023)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the FoFiType1C::cvtGlyph() function. A remote attacker can pass a specially crafted PDF file to the server, consume all available system resources and cause denial of service conditions.
