Security Advisories (6)
CVE-2016-1238 (2016-08-02)

Imager would search the default current directory entry in @INC when searching for file format support modules.

CVE-2008-1928 (2008-04-24)

Buffer overflow in Imager 0.42 through 0.63 allows attackers to cause a denial of service (crash) via an image based fill in which the number of input channels is different from the number of output channels.

CPANSA-Imager-2014-01 (2014-01-03)

When drawing on an image with an alpha channel where the source minimum is greater than zero, Imager would read from beyond the end of a malloc() allocated buffer. In rare circumstances this could lead to some of the source image not being written to the target image, or possibly to a segmentation fault.

CVE-2007-2459 (2007-05-02)

Heap-based buffer overflow in the BMP reader (bmp.c) in Imager perl module (libimager-perl) 0.45 through 0.56 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted 8-bit/pixel compressed BMP files.

CVE-2006-0053 (2006-04-10)

Imager (libimager-perl) before 0.50 allows user-assisted attackers to cause a denial of service (segmentation fault) by writing a 2- or 4-channel JPEG image (or a 2-channel TGA image) to a scalar, which triggers a NULL pointer dereference.

CVE-2024-53901 (2024-11-17)

"invalid next size" backtrace on use of trim on certain images

Changes for version 0.49_01

  • This is a test release specifically to fix #18397
  • correct warning in png.c from passing wrong pointer type to png_destroy_write_struct on line 173. fixes # 18051
  • Skip Inline tests when we're in a directory containing spaces in the path, since Inline itself errors out when used in such a directory. fixes # 18049
  • CRITICAL: writing a 2 or 4 channel image to jpeg or a 2 channel image to tga, where the output was a buffer chain would produce a segmentation fault during error handling and recovery. fixes # 18397
  • bump to 0.49_01 for test release
    • For latest versions check the Imager-devel pages: http://imager.perl.org/
