CVE-2026-93018

*** Pendiente de traducción *** Imager versions before 1.036 for Perl disclose uninitialised heap memory reading a paletted image with pixel indexes past its colour map in i_gpix_p and i_glin_p.<br /> <br /> The palette is allocated uninitialised, and only the entries a reader adds count as populated. The TGA reader stores pixel indexes without checking them against the colour map. i_gpix_p() rejects only an index greater than the count, so an index equal to it reads the first unpopulated entry, and getpixel() returns it.<br /> <br /> i_glin_p() skips any index at or beyond the count without writing that pixel to the caller&amp;#39;s buffer. The palette-to-RGB conversion reads each row through an uninitialised buffer, so those pixels of the converted image hold prior heap contents.<br /> <br /> Reading an attacker-supplied image through Imager-&gt;read() and then fetching its pixels or converting it to RGB discloses process heap memory.
