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.

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.

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 processDQT in jpgqguess.c.

jhead through 3.04 has a heap-based buffer over-read in Get32s when called from ProcessGpsInfo in gpsinfo.c.

An integer underflow bug in the processEXIF function of the exif.c file of jhead 3.00 raises a heap-based buffer over-read when processing a malicious JPEG file, which may allow a remote attacker to cause a denial-of-service attack or unspecified other impact.

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