Test ID:	1.3.6.1.4.1.25623.1.1.10.2020.0040
Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2020-0040)
Summary:	The remote host is missing an update for the 'libjpeg' package(s) announced via the MGASA-2020-0040 advisory.
Description:	Summary: The remote host is missing an update for the 'libjpeg' package(s) announced via the MGASA-2020-0040 advisory. Vulnerability Insight: The updated packages fix security vulnerabilities: A signed integer overflow and subsequent segfault that occurred when attempting to decompress images with more than 715827882 pixels using the 64-bit C version of TJBench. Out-of-bounds write in tjDecompressToYUV2() and tjDecompressToYUVPlanes() (sometimes manifesting as a double free) that occurred when attempting to decompress grayscale JPEG images that were compressed with a sampling factor other than 1 (for instance, with cjpeg -grayscale -sample 2x2). A regression introduced by 2.0.2[5] that caused the TurboJPEG API to incorrectly identify some JPEG images with unusual sampling factors as 4:4:4 JPEG images. This was known to cause a buffer overflow when attempting to decompress some such images using tjDecompressToYUV2() or tjDecompressToYUVPlanes(). An issue, detected by ASan, whereby attempting to losslessly transform a specially-crafted malformed JPEG image containing an extremely-high- frequency coefficient block (junk image data that could never be generated by a legitimate JPEG compressor) could cause the Huffman encoder's local buffer to be overrun. Affected Software/OS: 'libjpeg' package(s) on Mageia 7. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
