UBUNTU-CVE-2026-6791

When expanding paths that begin with a tilde followed by a username, the internal parsetilde function extracts the username to determine the user's home directory. The implementation allocates memory for this username directly on the stack using the strndupa macro. Because the size of this...

UBUNTU-CVE-2026-68187

In the Linux kernel, the following vulnerability has been resolved: exec: fix unsigned loop counter wrap in transferargstostack The stop value is derived from bprm-p PAGESHIFT. The index variable is an unsigned long. If bprm-p drops below PAGESIZE and stop becomes zero the loop condition index =...

CVE-2026-68159

In the Linux kernel, the following vulnerability has been resolved: libceph: bound pgtemp,upmap,upmapitems length to CEPHPGMAXSIZE decodepgtemp decodes an user-controlled length but only rejects values large enough to overflow the allocation; it does not bound it to CEPHPGMAXSIZE. The helper back...

CVE-2026-66485

GNU cpio is vulnerable to an uncontrolled memory allocation in the makepath function at src/makepath.c. The function uses alloca to allocate stack memory based on the length of argpath, which is derived from an archive-controlled pathname during extraction. A malicious cpio archive containing a...

CVE-2026-66485

GNU cpio is affected by an uncontrolled memory allocation in make_path (src/makepath.c) that uses alloca based on the length of argpath, derived from an archive-controlled pathname during extraction. A crafted cpio archive with a long nested pathname can trigger unbounded stack allocation, causin...

CVE-2026-66485 Uncontrolled Memory Allocation in GNU cpio

GNU cpio is vulnerable to an uncontrolled memory allocation in the makepath function at src/makepath.c. The function uses alloca to allocate stack memory based on the length of argpath, which is derived from an archive-controlled pathname during extraction. A malicious cpio archive containing a...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 7.1.2-16 and 6.9.13-41, there was a vulnerability where a memory allocation failure in the sixel encoder could lead to writing beyond the end of a buffer on the stack. This vulnerability...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 7.1.2-15 and 6.9.13-40, Magick failed to detect circular references between two MSLs, resulting in a stack overflow issue. Versions 7.1.2-15 and 6.9.13-40 include a patch to address this...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Versions prior to 7.1.2-13 have a potential security issue involving infinite recursion in the MSL Magick Scripting Language command when writing to MSL format. Version 7.1.2-13 addresses this issue...

Astra Linux – Vulnerability in xrdp

xrdp is an open-source RDP server. Before version 0.10.5, xrdp contained an unauthenticated stack-based buffer overflow vulnerability. The issue arises from improper bounds checking when processing user domain information during the connection process. If exploited, this vulnerability could allow...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a stack buffer overflow occurred when processing an attribute in the msl.c file. A long value overflowed a fixed-size stack buffer, resulting in memory...

Astra Linux – Vulnerability in Python 3.11

When an Expat parser with a registered ElementDeclHandler parses an inline document type definition containing a deeply nested content model, a C stack overflow occurs...

Astra Linux – Vulnerability in Systemd

Systemd, a system and service manager, as PID 1 encounters an assertion error and freezes execution when an unprivileged IPC API call is made with spurious data. In versions v249 and earlier, the effect is not an assertion error, but stack overwriting, with the content being controlled by the...
