# CVE-2026-93019

> 9.1 CRITICAL · 🧪 PoC

## Beschreibung

Imager versions before 1.036 for Perl exit the process reading a TGA with a colour map length of 32768 or more in tga_palette_read.

The reader unpacks the two-byte colour map length into a signed short, so a length of 32768 or more becomes negative. tga_palette_read() casts that value to size_t and asks mymalloc() for a size near SIZE_MAX. The allocation fails and Imager's allocator calls exit(3).

Reading an attacker-supplied file through Imager->read() triggers an uncatchable exit.

## Schwachstellen-Klasse

- **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.

## Angriffsmuster (CAPEC)
