Exploitability: 3.9 / Impact: 5.9
Source: 134c704f-9b21-4f2e-91b3-4a467353bcc0 (Secondary)
Description
Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed.
Imager mishandled large EXIF IFD entry count values, treating them as negative numbers. This could lead to an attempt to allocate a block nearly the size of the address space, which fails and kills the process.
An attacker could craft an image with EXIF data that terminates a worker process.

Related CWEs
CWE-196
Unsigned to Signed Conversion Error
The product uses an unsigned primitive and performs a cast to a signed primitive, which can produce an unexpected value if the value of the unsigned primitive can not be represented using a signed primitive.
CWE-789
Memory Allocation with Excessive Size Value
The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
