LibAST: Privilege escalation

Background LibAST is a utility library that was originally intended to accompany Eterm, but may be used by various other applications. Description Michael Jennings discovered an exploitable buffer overflow in the configuration engine of LibAST. Impact The vulnerability can be exploited to gain...

CVE-2005-4667

Buffer overflow in UnZip 5.50 and earlier allows user-assisted attackers to execute arbitrary code via a long filename command line argument. NOTE: since the overflow occurs in a non-setuid program, there are not many scenarios under which it poses a vulnerability, unless unzip is passed long...

Ubuntu 4.10 : perl vulnerabilities (USN-72-1)

Two exploitable vulnerabilities involving setuid-enabled perl scripts have been discovered. The package 'perl-suid' provides a wrapper around perl which allows to use setuid-root perl scripts, i.e. user-callable Perl scripts which have full root privileges. Previous versions allowed users to...

Ubuntu 4.10 : linux-source-2.6.8.1 vulnerabilities (USN-30-1)

CAN-2004-0883, CAN-2004-0949 : During an audit of the smb file system implementation within Linux, several vulnerabilities were discovered ranging from out of bounds read accesses to kernel level buffer overflows. To exploit any of these vulnerabilities, an attacker needs control over the answers...

Ubuntu 4.10 : evolution vulnerability (USN-69-1)

Max Vozeler discovered an integer overflow in camel-lock-helper. An user-supplied length value was not validated, so that a value of -1 caused a buffer allocation of 0 bytes; this buffer was then filled by an arbitrary amount of user-supplied data. A local attacker or a malicious POP3 server coul...

Mandrake Linux Security Advisory : fuse (MDKSA-2005:216)

Thomas Beige found that fusermount failed to securely handle special characters specified in mount points, which could allow a local attacker to corrupt the contents of /etc/mtab by mounting over a maliciously-named directory using fusermount. This could potentially allow the attacker to set...

Ubuntu 4.10 : linux-source-2.6.8.1 vulnerability (USN-39-1)

USN-30-1 fixed several flaws in the Linux ELF binary loader's handling of setuid binaries. Unfortunately it was found that these patches were not sufficient to prevent all possible attacks on 64-bit platforms, so previous amd64 kernel images were still vulnerable to root privilege escalation if...

Ubuntu 4.10 : perl vulnerability (USN-94-1)

Paul Szabo discovered another vulnerability in the rmtree function in File::Path.pm. While a process running as root or another user was busy deleting a directory tree, a different user could exploit a race condition to create setuid binaries in this directory tree, provided that he already had...

Mandrake Linux Security Advisory : uim (MDKSA-2005:198)

Masanari Yamamoto discovered that Uim uses environment variables incorrectly. This bug causes a privilege escalation if setuid/setgid applications are linked to libuim. The updated packages have been patched to address this issue. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descripti...

Design/Logic Flaw

The dupfdopen function in sys/kern/kerndescrip.c in OpenBSD 3.7 and 3.8 allows local users to re-open arbitrary files by using setuid programs to access file descriptors using /dev/fd/...

DEBIAN-CVE-2005-4667

Buffer overflow in UnZip 5.50 and earlier allows user-assisted attackers to execute arbitrary code via a long filename command line argument. NOTE: since the overflow occurs in a non-setuid program, there are not many scenarios under which it poses a vulnerability, unless unzip is passed long...

CVE-2005-4741

NetBSD 1.6, NetBSD 2.0 through 2.1, and NetBSD-current before 20051031 allows local users to gain privileges by attaching a debugger to a setuid/setgid PSUGID process that performs an exec without a reset of real credentials...

GLSA-200512-17 : scponly: Multiple privilege escalation issues

The remote host is affected by the vulnerability described in GLSA-200512-17 scponly: Multiple privilege escalation issues Max Vozeler discovered that the scponlyc command allows users to chroot into arbitrary directories. Furthermore, Pekka Pessi reported that scponly insufficiently validates...

CVE-2005-4532

scponlyc in scponly 4.1 and earlier, when the operating system supports LDPRELOAD mechanisms, allows local users to execute arbitrary code with root privileges by creating a chroot directory in their home directory, hard linking to a system setuid application, and using a modified LDPRELOAD to...

CVE-2005-4532

CVE-2005-4532 affects scponly versions 4.1 and earlier. The root cause is a design/implementation flaw in scponlyc that can be exploited when LD_PRELOAD is available: an unprivileged user can create a chroot directory in their home, hard-link to a system setuid application, and override expected ...

scponly -- local privilege escalation exploits

Max Vozeler reports: If ALL the following conditions are true, administrators using scponly-4.1 or older may be at risk of a local privilege escalation exploit: the chrooted setuid scponlyc binary is installed regular non-scponly users have interactive shell access to the box a user executable...

security flaw

Race condition in the rmtree function in File::Path.pm in Perl before 5.8.4 allows local users to create arbitrary setuid binaries in the tree being deleted, a different vulnerability than CVE-2004-0452...

CVE-2005-4082

The dhcp.client program for QNX 4.25 vmware is setuid, possibly by default, which allows local users to modify the NIC configuration and conduct other attacks...

GLSA-200511-17 : FUSE: mtab corruption through fusermount

The remote host is affected by the vulnerability described in GLSA-200511-17 FUSE: mtab corruption through fusermount Thomas Biege discovered that fusermount fails to securely handle special characters specified in mount points. Impact : A local attacker could corrupt the contents of the /etc/mta...

CVE-2004-2611

The Change Permissions function in the Sophster suite before 0.9.6 28 May 2004 aka 0.9.6-r5, possibly including Sophster, FreeSophster, and FreeSophsterPAM, removes the 1 setuid, 2 setgid, and 3 sticky bits when changing a file, which might allow attackers to gain privileges or conduct other...
