Vulnerabilidades

A security vulnerability has been detected in Matthias-Wandel jhead up to 3.3. This impacts the function ProcessGpsInfo of the file gpsinfo.c of the component WebP EXIF Handler. Such manipulation of the argument TAG_GPS_LAT/TAG_GPS_LONG leads to heap-based buffer overflow. An attack has to be approached locally. The…

A weakness has been identified in Matthias-Wandel jhead up to 3.3. This affects the function Get16u of the file exif.c of the component EXIF Parsing. This manipulation causes out-of-bounds read. The attack requires local access. The exploit has been made available to the public and could be used for attacks. The…

jhead v3.08 was discovered to contain a heap-use-after-free via the ProcessFile function at jhead.c.

A vulnerability was found in Matthias-Wandel jhead 3.08 and classified as critical. This issue affects the function PrintFormatNumber of the file exif.c. The manipulation leads to heap-based buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The…

Buffer Overflow vulnerability in jpgfile.c in Matthias-Wandel jhead version 3.04, allows local attackers to execute arbitrary code and cause a denial of service (DoS).

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`…

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 vulnerability exists in jhead 3.04 and 3.05 via the RemoveSectionType function in jpgfile.c.

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 via a wild address read in the ProcessCanonMakerNoteDir function in makernote.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.

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…

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 Get32s when called from ProcessGpsInfo in gpsinfo.c.

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

jhead 3.03 is affected by: heap-based buffer over-read. The impact is: Denial of service. The component is: ReadJpegSections and process_SOFn in jpgfile.c. The attack vector is: Open a specially crafted JPEG file.

jhead 3.03 is affected by: Incorrect Access Control. The impact is: Denial of service. The component is: iptc.c Line 122 show_IPTC(). The attack vector is: the victim must open a specially crafted JPEG file.

jhead 3.03 is affected by: Buffer Overflow. The impact is: Denial of service. The component is: gpsinfo.c Line 151 ProcessGpsInfo(). The attack vector is: Open a specially crafted JPEG file.

The ProcessGpsInfo function of the gpsinfo.c file of jhead 3.00 may allow a remote attacker to cause a denial-of-service attack or unspecified other impact via a malicious JPEG file, because there is an integer overflow during a check for whether a location exceeds the EXIF data length. This is analogous to the…

The ProcessGpsInfo function of the gpsinfo.c file of jhead 3.00 may allow a remote attacker to cause a denial-of-service attack or unspecified other impact via a malicious JPEG file, because of inconsistency between float and double in a sprintf format string during TAG_GPS_ALT handling.

An integer underflow bug in the process_EXIF 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.

The DoCommand function in jhead.c in Matthias Wandel jhead 2.84 and earlier allows attackers to execute arbitrary commands via shell metacharacters in unspecified input.

The DoCommand function in jhead.c in Matthias Wandel jhead 2.84 and earlier allows local users to delete arbitrary files via vectors involving a modified input filename in which (1) a final "z" character is replaced by a "t" character or (2) a final "t" character is replaced by a "z" character.

jhead.c in Matthias Wandel jhead 2.84 and earlier allows local users to overwrite arbitrary files via a symlink attack on a temporary file.
