KDE Okular PDB image.cpp buffer overflow
|okularpdb-imagecpp-bo (61371)||High Risk|
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.
Apply the patch for this vulnerability (KDE SC 4.3, branch: r1167825, KDE SC 4.4 branch: r1167826, or KDE SC 4.5 branch: r116782), available from the KDE Web site. See References.
