PatchTheCVECVE-2026-19082: Imager versions from 0.45_02 before 1.034 for Perl may expose adjacent heap bytes via strlen() over-read from
CVE-2026-19082 is a high-severity flaw (CVSS 7.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Imager versions from 0.45_02 before 1.034 for Perl may expose adjacent heap bytes via strlen() over-read from zero-count ASCII EXIF entries in copy_string_tags. copy_string_tags() computes an ASCII EXIF tag's length as `entry->size - 1` to strip the trailing NUL. A zero-count ASCII entry sets `entry->size` to 0, and the derived length reaches i_tags_add() as -1, which is interpreted as a request to call strlen(), scanning past the entry to the n
Why this priority
- High severity
- CISA SSVC: public proof of concept
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
