- Ubuntu 14.04 LTS (Available with Ubuntu Pro)

Summary:

Several security issues were fixed in LibTIFF.

Software Description:
- tiff: Tag Image File Format (TIFF) library

Details:

It was discovered that LibTIFF could be made to write out of bounds when
processing certain malformed image files with the tiffcrop utility. If a
user were tricked into opening a specially crafted image file, an attacker
could possibly use this issue to cause tiffcrop to crash, resulting in a
denial of service, or possibly execute arbitrary code. This issue only
affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS.
(CVE-2022-48281)

It was discovered that LibTIFF incorrectly handled certain image files. If
a user were tricked into opening a specially crafted image file, an
attacker could possibly use this issue to cause a denial of service. This
issue only affected Ubuntu 23.04. (CVE-2023-2731)

It was discovered that LibTIFF incorrectly handled certain image files
with the tiffcp utility. If a user were tricked into opening a specially
crafted image file, an attacker could possibly use this issue to cause
tiffcp to crash, resulting in a denial of service. (CVE-2023-2908)

It was discovered that LibTIFF incorrectly handled certain file paths. If
a user were tricked into specifying certain output paths, an attacker
could possibly use this issue to cause a denial of service. This issue
only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2023-3316)

It was discovered that LibTIFF could be made to write out of bounds when
processing certain malformed image files. If a user were tricked into
opening a specially crafted image file, an attacker could possibly use
this issue to cause a denial of service, or possibly execute arbitrary
code. (CVE-2023-3618)

It was discovered that LibTIFF could be made to write out of bounds when
processing certain malformed image files. If a user were tricked into
opening a specially crafted image file, an attacker could possibly use
this issue to cause a denial of service, or possibly execute arbitrary
code. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and
Ubuntu 23.04. (CVE-2023-25433, CVE-2023-26966)

It was discovered that LibTIFF did not properly managed memory when
processing certain malformed image files with the tiffcrop utility. If a
user were tricked into opening a specially crafted image file, an attacker
could possibly use this issue to cause tiffcrop to crash, resulting in a
denial of service, or possibly execute arbitrary code. This issue only
affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04.
(CVE-2023-26965)

It was discovered that LibTIFF contained an arithmetic overflow. If a user
were tricked into opening a specially crafted image file, an attacker
could possibly use this issue to cause a denial of service.
(CVE-2023-38288, CVE-2023-38289)
