libvips before 8.7.4 generates output images from uninitialized memory locations when processing corrupted input image data because iofuncs/memory.c does not zero out allocated memory. This can result in leaking raw process memory contents through the output image.
AnalysisAI
libvips before 8.7.4 generates output images from uninitialized memory locations when processing corrupted input image data because iofuncs/memory.c does not zero out allocated memory. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Use of Uninitialized Resource vulnerability could allow attackers to access uninitialized memory causing crashes or information disclosure.
Technical ContextAI
This vulnerability is classified as Use of Uninitialized Resource (CWE-908), which allows attackers to access uninitialized memory causing crashes or information disclosure. libvips before 8.7.4 generates output images from uninitialized memory locations when processing corrupted input image data because iofuncs/memory.c does not zero out allocated memory. This can result in leaking raw process memory contents through the output image. Affected products include: Libvips. Version information: before 8.7.4.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Initialize all variables, use compiler warnings for uninitialized access, use memory-safe languages.
