Description
This security bulletin contains information about 5 vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2018-7998)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 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/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the vips_region_generate() function in region.c in the libvips library. A remote attacker can pass specially crafted input to the library and perform a denial of service (DoS) attack.
2) Memory leak (CVE-ID: CVE-2019-6976)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due memory leak within the iofuncs/memory.c file in libvips library due to application does not zero out allocated memory when when processing corrupted input image data. A remote attacker can pass to the application a corrupted data and leak raw process memory contents through the output image.
3) Information disclosure (CVE-ID: CVE-2020-20739)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in "im_vips2dz" in "/libvips/libvips/deprecated/im_vips2dz.c". A remote attacker can gain unauthorized access to sensitive information on the system.
4) Division by zero (CVE-ID: CVE-2021-27847)
CWE-ID: CWE-369 - Divide By Zero
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 ti a division by zero error within the vips_eye_point() function in eye.c. A remote attacker can pass specially crafted input to the affected application and perform a denial of service (DoS) attack.
5) NULL pointer dereference (CVE-ID: CVE-2023-40032)
CWE-ID: CWE-476 - NULL Pointer Dereference
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 a NULL pointer dereference error when parsing a malformed UTF-8 character inside an SVG files. A remote attacker can pass specially crafted SVG file to the application and perform a denial of service (DoS) attack.
