An issue was discovered in Artifex Ghostscript before 10.05.0. A buffer overflow occurs during serialization of DollarBlend in a font, for base/write_t1.c and psi/zfapi.c.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-908 advisory.

    Potential integer and buffer overflow with DollarBlend during serializing a multiple master font for     passing to Freetype. Fixed by changing a variable type from short to unsigned short and checking if a     length variable exceeds permitted limit.Fixed in ghostpdl-10.05.0 (CVE-2025-27830)

    Text buffer overflow with long characters; the txt_get_unicode function was copying too few bytes from the     fixed glyph name to unicode mapping tables. This was probably causing incorrect Unicode code points in     relatively rare cases but not otherwise a problem. However, a badly formed GlyphNames2Unicode array     attached to a font could cause the decoding to spill over the assigned buffer.

    Patched in ghostpdl-10.05.0 (CVE-2025-27831)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of ghostscript installed on the remote host is prior to 9.54.0-9. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2805 advisory.

    Patched in ghostpdl-10.05.0 (CVE-2025-27831)

    The calculation of the buffer size was being done with int values, and overflowing that data type. The bug     has existed since the creation of the file contrib/japanese/gdevnpdl.cThe calculation of the buffer size     was being done with int values, and overflowing that data type. By leaving the total size calculation to     the memory manager, the calculation ends up being done in size_t values, and avoiding the overflow in this     case, but also meaning the memory manager overflow protection will be effective.

    Fixed in ghostpdl-10.05.0

    (CVE-2025-27832)

    It was discovered that Ghostscript incorrectly handled certain long TTF file names. An attacker could use     this issue to cause Ghostscript to crash, resulting in a denial of service, or possibly execute arbitrary     code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 24.10. (CVE-2025-27833)

    It was discovered that Ghostscript incorrectly handled oversized Type 4 functions in certain PDF     documents. An attacker could use this issue to cause Ghostscript to crash, resulting in a denial of     service, or possibly execute arbitrary code.

    Multiple security issues were discovered in Ghostscript, the GPL     PostScript/PDF interpreter, which could result in denial of service and     potentially the execution of arbitrary code if malformed document files     are processed.

    For the stable distribution (bookworm), these problems have been fixed in     version 10.0.0~dfsg-11+deb12u7.

    We recommend that you upgrade your ghostscript packages.
