Comment 1 Marek Kašík 2025-09-04 15:36:52 UTC 
Looking at the https://www.cve.org/CVERecord?id=CVE-2025-50422, it points me to the https://gitlab.freedesktop.org/poppler/poppler/-/issues/1591. When I reproduce this "crash" it gets me to a code which states that this "abort" is actually caused by a memory leak related to fonts. See comment at https://gitlab.freedesktop.org/poppler/poppler/-/blob/master/utils/pdftocairo.cc?ref_type=heads#L1289 .
I've tried to find the leak but unsuccessfully so far.
