Linux Distros Unpatched Vulnerability : CVE-2026-93019

critical Nessus Plugin ID 348214

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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. (CVE-2026-93019)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
