UBUNTU-CVE-2026-63275

LibreOffice can read CFF fonts, which may be embedded in documents. A stack buffer overflow existed when reading the hints of a glyph. The number of hints was checked against the wrong bound, so a glyph declaring more hints than the array can hold wrote past its end. In fixed versions the hint...

UBUNTU-CVE-2026-63276

LibreOffice converts CFF fonts to Type 1 when it subsets a font, which happens when a document is exported to PDF, and CFF fonts may be embedded in documents. A stack buffer overflow existed in that conversion. The converted operators were written into a fixed size buffer with no check that they...

UBUNTU-CVE-2026-61822

pgpartman is a PostgreSQL extension that manages partitioned tables by time or ID. Prior to 5.5.0, runmaintenance handles exceptions outside the loop that processes rows from partconfig, so an exception for one partition set immediately terminates the loop and skips every later set. A role with...

UBUNTU-CVE-2026-93586

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a use-after-free vulnerability in the ImagesToBlob method, caused by a pointer that is not updated correctly. Exploitation may result in a limited availability impact e.g., a crash of the affected process. The issue is fixed in versions...

UBUNTU-CVE-2026-93019

Imager versions before 1.036 for Perl exit the process reading a TGA with a colour map length of 32768 or more in tgapaletteread. The reader unpacks the two-byte colour map length into a signed short, so a length of 32768 or more becomes negative. tgapaletteread casts that value to sizet and asks...
