Description
This security bulletin contains information about 7 vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2018-19107)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Exiv2 0.26, Exiv2::IptcParser::decode in iptc.cpp (called from psdimage.cpp in the PSD image reader) may suffer from a denial of service (heap-based buffer over-read) caused by an integer overflow via a crafted PSD image file.
2) Infinite loop (CVE-ID: CVE-2018-19108)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Exiv2 0.26, Exiv2::PsdImage::readMetadata in psdimage.cpp in the PSD image reader may suffer from a denial of service (infinite loop) caused by an integer overflow via a crafted PSD image file.
3) Out-of-bounds read (CVE-ID: CVE-2018-19535)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Exiv2 0.26 and previous versions, PngChunk::readRawProfile in pngchunk_int.cpp may cause a denial of service (application crash due to a heap-based buffer over-read) via a crafted PNG file.
4) Integer overflow (CVE-ID: CVE-2019-13110)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 4.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to integer overflow in CiffDirectory::readDirectory() function. A remote attacker can create a specially crafted CRW image, pass it to the application, trigger integer overflow and crash the affected application.
5) Resource management error (CVE-ID: CVE-2019-13112)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: 4.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to memory allocation error in PngChunk::parseChunkContent() function. A remote attacker can create a specially crafted PNG image, pass it to the application and perform a denial of service attack.
6) Reachable Assertion (CVE-ID: CVE-2019-13113)
CWE-ID: CWE-617 - Reachable Assertion
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 perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion due to assertion failure) via an invalid data location in a CRW image file. A remote attacker can cause a denial of service (crash.
7) NULL pointer dereference (CVE-ID: CVE-2019-13114)
CWE-ID: CWE-476 - NULL Pointer Dereference
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 perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error when parsing HTTP responses without a space character. A remote attacker can perform a denial of service (DoS) attack.
