1) Resource exhaustion (CVE-ID: CVE-2018-10801)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

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:P/U:Clear


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

The vulnerability exists due to insufficient validation of user-supplied input processed by the TIFFClientOpen function, as defined in the tif_unix.c source code file. A remote attacker can use the .bmp2tiff command to execute a file that submits malicious input to the system, trigger memory leaks and cause the affected software to crash, resulting in a DoS condition.
