Summary
Moderate: libwebp security update
Details

The libwebp packages provide a library and tools for the WebP graphics format. WebP is an image format with a lossy compression of digital photographic images. WebP consists of a codec based on the VP8 format, and a container based on the Resource Interchange File Format (RIFF). Webmasters, web developers and browser developers can use WebP to compress, archive, and distribute digital images more efficiently.

Security Fix(es):

  • libwebp: out-of-bounds read in WebPMuxCreateInternal (CVE-2018-25009)

  • libwebp: out-of-bounds read in ApplyFilter() (CVE-2018-25010)

  • libwebp: out-of-bounds read in WebPMuxCreateInternal() (CVE-2018-25012)

  • libwebp: out-of-bounds read in ShiftBytes() (CVE-2018-25013)

  • libwebp: use of uninitialized value in ReadSymbol() (CVE-2018-25014)

  • libwebp: out-of-bounds read in ChunkVerifyAndAssign() in mux/muxread.c (CVE-2020-36330)

  • libwebp: out-of-bounds read in ChunkAssignData() in mux/muxinternal.c (CVE-2020-36331)

  • libwebp: excessive memory allocation when reading a file (CVE-2020-36332)
