Matthias-Wandel/jhead jhead 3.06 is vulnerable to Buffer Overflow via shellescape(), jhead.c, jhead. jhead copies strings to a stack buffer when it detects a &i or &o. However, jhead does not check the boundary of the stack buffer. As a result, there will be a stack buffer overflow problem when multiple `&i` or `&o` are given.

jhead 3.06 is vulnerable to Buffer Overflow via exif.c in function Put16u.

Jhead 3.06.0.1 allows attackers to execute arbitrary OS commands by placing them in a JPEG filename and then using the regeneration -rgt50 option.

A Heap-based Buffer Overflow vulnerabilty exists in jhead 3.04 and 3.05 is affected by: Buffer Overflow via the RemoveUnknownSections function in jpgfile.c.

A Denial of Service vulnerability exists in jhead 3.04 and 3.05 due to a wild address read in the Get16u function in exif.c in will cause segmentation fault via a crafted_file.

A Denial of Service vulnerability exists in jhead 3.04 and 3.05 via a wild address read in the ProcessCanonMakerNoteDir function in makernote.c.

A Heap-based Buffer Overflow vulnerability exists in jhead 3.04 and 3.05 via the RemoveSectionType function in jpgfile.c.

JHEAD is a simple command line tool for displaying and some manipulation of EXIF header data embedded in Jpeg images from digital cameras. In affected versions there is a heap-buffer-overflow on jhead-3.04/jpgfile.c:285 ReadJpegSections. Crafted jpeg images can be provided to the user resulting in a program crash or potentially incorrect exif information retrieval. Users are advised to upgrade. There is no known workaround for this issue.

A heap-based buffer overflow was found in jhead in version 3.06 in Get16u() in exif.c when processing a crafted file.

jhead through 3.04 has a heap-based buffer over-read in process_DQT in jpgqguess.c.
