KDE Okular PDB image.cpp buffer overflow
| okularpdb-imagecpp-bo (61371) |  High Risk |
Description:
KDE Okular PDB is vulnerable to a heap-based buffer overflow, caused by improper bounds checking within the RLE decompression in the TranscribePalmImageToJPEG() function. By persuading a victim to open a specially-crafted PDB file, an attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
